Today, a friend asked if I had an extra laptop. He needed one for his 10 year old son.
While rummaging through my closet (you know, the one with all the old computers, shotguns, and half empty Jack Daniels bottles) when I found one of these.
Two Pics … http://db.tt/GY4wfof6 and http://db.tt/rzkodoMi
Now, I have no idea as to how, where or when I got this. I had to search the net to even know what it was.
Ebay link … http://www.ebay.com/itm/230328510631?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2648
Continuing my search of the closet I also found a 2.5 inch 160 gig IDE hard drive. Assembled the two and I now have a portable battery powered drive that works great with my Flyer.
That looks kinda old school. =)
So you connect to the flyer via bluetooth or microUSB?
It connects with microUSB.
Now that I’ve had a chance to use it a while I’ve found I can set its switch to PC or DC.
When set to PC I just plug it in to my Flyer and can copy files both ways.
When set to DC it will function as a standalone unit (because it has its own battery power). I can plug thumb drives and USB sdcard adaptors into it to move files both ways.
It will even plug into my camera and copy the pictures.
Kind of handy as the Flyer doesn’t supply power at its microUSB port to spin a hard drive.
It’s not what I call well built but seems to work.
At least it does the job! I didn't know we could use OTG harddrive for the flyer...
That's very cool. Vastly increases the number of movies I could take with me on a long trip!
ARRR
Ok so spent about £40 on one of these and it doesn't work with my Flyer(32GB WiFi 3G). Flyer is not rooted and running the latest official version of HC. I have tried both DC and PC but device still does not detect the OTG drive. My samsung mobile finds the device fine.
Are you using a standard micro usb cable ??

Yes using a standard micro usb cable
Try this ... Shut down your Flyer (make sure Fast Boot is unchecked in settings) then turn on your drive in DC mode and restart your Flyer.
Your Flyer should find it then and will work from then on.
Using your file explorer of choice you should see a new folder called USB
Hi, tried this but still no go. Ran a USB host and USB OGB diganostics app which still fail to detect the device. The drive works with my camera/Samsung phone and brothers PSP. May have to fork out for WIFI drive.
Still no go with the OTG device. Tried with a friends Flyer and same results. I am going to try this device, is fairly cheap.

I have an OTG cable from my samsung but this did not work. what OTG cable are you using? I gather you are connecting the USB device into the OTG cable via a powered hub?
Got it working but it's a hackjob, was going to root but having to downgrade then upgrade again was a pain and was not guaranteed to work. Tried running the OTG cable into a powered hub but for what ever reason would always come up USB device not recognised when plugging in any memory device. Tried 3 USB hubs with the same result. Ended up cutting up an OTG cable and a few other USB cables so I could provide power to the device and then power to the tablet as well. For whatever reason i need to provide power to he memory stick before plugging into tablet. I have tested 4 different memory pens and 1 external harddrive and they all work.
I just bought a generic OTG cable, its about 6 inches long. I think it may have come from HP. I have used both a powered hub and a y-usb hard drive cable and both worked for me.
You have to have power on the device before you plug it onto the FLyer so that on connect the Flyer software knows what type of device it is and can load the driver. Otherwise the Flyer will label it unknown and disable the device.
Managed to get USB on the go to work on my Jetstream. See the following post. as the flyer very similar, should work for flyer too.

Hi everyone,
and thanks in advance for any help / advice that you may have for me.
I'll start off with my question, before I unload all of my information. I simply would like to know exactly what type of USB Connection the Sony Tablet has, and therefore, what specific USB Cable I need to buy in order to connect it to my PC running Vista.
I bought a Sony Tablet and have been surprised the lack of information in regards to the USB connectivity of the device. Specifically, the exact 'cable type' required to connect the device to a PC. Everywhere I have read so far, it simply says USB Micro, or USB 2.0 micro. But when I try use the micro USB cable that I currently use with my Xperia Play phone (which works fine for PC transfer with the phone) it's doesn't work at all with the Sony Tablet. It doesn't even register on the PC when I plug the cable into the tablet. Just nothing.
Since then, I have read a lot about USB, and found that there are different types, like 'Mini USB' versus 'Micro USB'. Apparently there is also Micro USB 'A' and Micro USB 'B'. And finally, apparently there is 4 pin micro usb and 5 pin micro usb type.
hope this all makes sense, many thanks guys.
Austab.
This tablet uses micro USB, I'm pretty sure the cable for your Xperia should work fine with the tablet. Perhaps you plugged it in upside down?
Thanks for the reply, I agree with your thought train. If it works with the Xperia, then surely it should work with tablet. I'll try it again after work today, and confirm. Is it actually possible to plug the cable in the wrong way around?
I'll kick myself if I did! Thanks again, cheers.
Austab.
It cannot be plugged in upside down, unless you use extreme force and break it.
***
But yeah, this cable *should work, if it works with your Xperia Play. In principle there is only one kind of micro-USB cable (well, actually it could have either regular type A *OR micro type A connector at one end, but let's keep it simple. Mini-USB is a different kind and A and B are just connector types.
See this picture with different USB connectors:
http://en.wikipedia.org/wiki/File:Types-usb_new.svg
Your cable should have a regular USB A connector (the one on the top left) at one end and micro-USB B connector at the other end (the one on the bottom right).
Yeah, it should work; I'm using the same USB cable that I use with my Xperia Arc.
For what it's worth, I've been having issues too. Mostly windows fails to find the drivers and install them. I've talked to multiple Sony reps and have tried multiple computers but haven't had any luck. Maybe it's a bad cable but I have had Windows detect the device...just unable to install the plug-n-play drivers.
Systems I've tried it on:
Custom built - Windows 7 with Service Pack 1
Dell - Windows XP Service Pack 3
Sony Vaio Laptop - Windows XP Service Pack 3
I had the same problem on both of tablet P and tablet S. I can tell you, its more about luck than the wrong cable type! At the end, it just works after retrying a few plugs and unplugs.
Hope they can get a fix for this soon.
Hey again guys, I've now tried the cable again with my Sony Tablet, and I'm definitely plugging it in correctly. There's no response whatsoever on the tablet or the PC once I've plugged the cable in.
When using the same cable on my Xperia play, the phone will instantly start charging once I plug the cable in to the PC. However, the PC doesn't actually recognize the phone as a device (i.e. it doesn't show up in windows explorer, or launch the Ericsson Phone Software, as it once did). It charges the phone, but doesn't talk to it, if that makes sense.
So it would seem that some Micro USB cables are good for charging only, but not for data transfer / PC recognition.
I'll buy a different cable tomorrow so will let you know if it works then.
Thanks again for all the replies guys I appreciate it.
cheers again,
Austab
Looks like the cable is faulty then and you have to try another one.
I bet one of data wires is broken, or a data contact inside connector is broken (worn down), because when you connect your Xperia Play it should also be recognized as a device.
Then again, maybe there is something wrong with your computer.
Can you try the same cable on another computer, and see if the device is recognized, before you buy a new cable. Or let them check the cable at the store to see if it really is faulty.
My understanding is you need an OTG USB cable, (On The Go) - this is what you need to connect USB keys and other hard-drives and so therefore I would think external PCs too.
I bought a nokia one for around 5 pounds from amazon, do a search for OTG USB cables,
thanks
Pratish
He wants to connect it to a computer, not connect external devices to it.
So he needs a regular micro-USB cable.
the cable is USB Host finde with this name
People, wtf are you talking?!
He *does not* need USB host (OTG) cable. That's for connecting USB devices, like keyboard, mouse, USB-storage etc., to your tablet.
He wants to connect his tablet to a computer. For that he needs a regular type A USB to type B micro-USB cable.
Hi,
Would seem like op had a charging cable, not data one. As stated, he need a regular data cable with appropriate connectors. OTG has nothing to do with it.

Hi Crazzzik,
so you're saying that there are micro usb cables for charging only, and then there are micro usb cables for data + charging etc? That would explain things perfectly for me, as my cable seems to work for charging devices, but not communicating with a PC (i.e. data transfer).
I'm getting a new cable today - sorted!
Many thanks everyone for your help & advice
Austab
Yes when I got the cable for my sony tablet s, I saw several usb cables that would fit the tablet, but on the package it said specifically "for charging only, not meant for data transfer", so they do make the cabkes just for charging, as a PC tech, I was a little embarrassed that I just found this out this weekend.
Thanks
I also got a microUSB-cable adapter, it works fine with usb driver / joypad and keyboard
but not sure if it's capable for connecting with PC or even for charging
hello all,
I recently bought the usb cable for the tablet they sell at the sony store. The micro usb to female normal usb ( I think you know what im talking about). It is sony tablet specific. The micro usb end of the cable is square instead of tappered at one side. it worked fantastic for plugging in and usb deviced to the tablet, but when I tried to plug it into my galaxy s, it wouldn't fit. just thought those thinking of buying one would appreciate the heads up so its not a shock if they try to use it on any other devices. Im sure you can find that same cable at any well stocked computer shop.
i borrowed a htc wildfire s cable, this works and installs drivers.
As some of you know, I could get USB host to work on the release candidate of HoneyComb but not on the final release (3.55.405).
This morning I thought I would try again, my flyer was turned off (completely shut down) when I plugged in my portable hard drive (Seagate 120 gig using the Y cable one to a power supply the other to a USB micro USB adaptor).
I then booted up the Flyer … low and behold there it was. Shows up as USB in Astro but, does not show in Root Explorer.
I was able to watch my movies and play my music from the hard drive.
It seems like the flyer with latest HoneyComb will only see USB peripherals at boot time.
Great news!
If you care to try some other configurations, I'd love to get your results when using a usb keyboard or mouse?

I don´t use a custom rom I use the HC stock rom. You have to have the "/mnt/sdcard/usb/" folder. If you don´t have it, create it. I use only as I mentioned a 1 TB Harddisk and I used also two different kind of 8GB USB Flashdrives with a Y-Cable with external powersupply and a Nokia OTG Cable.
They work all perfectly fine. Only I had to unmount the devices before I unplugged otherwise I needed to reboot as well for a another usb device.
I didn´t try any other peripherals.
I am not a "tecfreak", just an average user who likes to tinker and mess around with his gadgets. If you have any further question I can help you with, Please ask.
P.S.: before I used the Nokia Cable, I used another Micro USB Male to USB A Female Cable and that didn´t work, so If it doesn´t work for you than it might be caused by the wrong cable. ????

Been doing some more testing … I noticed (when using the Y cable on my drive) that when I power up the hard drive the charging light on the Flyer comes on.
So, somehow power is back feeding to the OTG cable.
This leads me to believe that it may work better (like Elfuente stated) with a different cable.
Perhaps the Nokia cable does not have the charging pins
Ps: I noticed that on my Y cable … one is labeled Power+Data the other is labeled Power
I had a rather long message typed about this but the browser crashed, I'll possibly retype most of that later, but for now suffice to say that cables are singnificant in these setups.

Ahhh there you are I was hoping you would show up. If anyone could shed some light on this it would be you. Do I smell another hardware hack?
Keeping in mind my abilities in this field are very limited but, I was thinking … if I could come up with a battery pack for a portable hard drive I could (with the proper cables) then just plug it in and have the ability to read and write to it.
Maybe another hack for an adapter to provide power from a battery with usb connector or mains usb charger but it should actually be fairly trivial to implement, so maybe a schematic also for anyone who is remotely comfortable with soldering.
The big difference between OTG and other usb modes is that pin 5 is electrically significant. When grounded it indicates to an otg capable device that it should go to OTG-A mode (OTG equivalent of host mode), when floating it's ignored and the device will not detect a connected device.

That´s exactly what I do. I travel a lot and was used to carry a netbook with me. Now I changed to the Flyer and use the external 1TB Harddisc with a BatteryPack as external powersupply (http://www.amazon.de/gp/product/B003ZV1A1Y).
As I already mentioned: It works fine for me.

I ordered one of the Nokia cables and if it works for me.
I’ll then take both apart (drive and battery) and mill up a case to mount both of them in.
This only works with honey comb right?
and by the way, the disc has to be formated wit fat32.

Thanks to a recent video by reverendkjr on Youtube, we now have a confirmed USB OTG method for CM9.
http://www.youtube.com/watch?v=Nc7tlPwFQpg
This has lots of potential and since I did not see much talk about it here, I decided to create a thread with what you need to buy listed in reverendkjr's video and what works. I would recommend only buying from Amazon Fulfilled sellers as they are backed by Amazon's return policy. All 3 items only cost a little over $10.

You can use whatever source of USB power you want including a wall charger, but I bought the 2AA battery powered supply above and can confirm it works.
Compatibility List:
-Multiple USB devices will work if you use a USB hub. A non-powered one works fine for me since you will already have a separate power source.
-USB keyboards and mice work fine including all basic functions like scroll wheel on the mouse, num and caps lock on the keyboard.
-FAT32 formatted flash drives will mount by default under "/mnt/usbdisk".
(Added September 7th)
-If you want to mount NTFS drives or multiple flash drives, download Drive Mount. This software will mount drives under "/mnt/sda1", "/mnt/sdb1", etc. I can confirm it works for multiple drives and NTFS/FAT32. It was removed from Google Play so the apk has been posted. If anybody has had success with other NTFS mounting software please post your results.

-I tried a Rosewill USB SATA/IDE externally powered hard drive reader and was able to mount a 400GB SATA 3.5" HDD using Drive Mount. Just to see what would happen I tried a SATA DVD drive but Android doesn't recognize it and probably doesn't even support the CD/DVD file system.
(Added April 7th)
-USB card readers will work, but I've had mixed results.
USB Device Info:
If you want to diagnose items and see some info about what the Touchpad is detecting, download USB Device Info free from Google Play. Everything shows up under the Linux tab. This shows some useful info about devices including current draw, device identification, etc. I tested it with a USB hub and a few flash drives and it successfully showed entries for the hub and the flash drives. It wont tell you if Android has drivers for the device, but merely IDs the device(s) confirming the connection if working.
(Added Dec 9th)
A plugged in USB OTG adapter will show up as "Qualcomm On-Chip EHCI Host Controller" under the Linux tab regardless of whether or not power is present. This is a good way to see if you have a working OTG adapter.
Flash Drive Unmounting Issues:
Flash drives are called an SD Card when mounted. There is no option to unmount a flash drive unless you use Drive Mount, so if you notice SD card removal error messages they are referring to your flash drive and not the Touchpad's internal memory partition that is mounted as /sdcard.
When a flash drive is removed or powered off without being unmounted, its common to get a "android.process.media" force close, just tap OK.
Charging:
You will not be able to charge via micro USB while using OTG even if your power source has enough current. You can charge via the Touchstone just fine. Knowing this, you can set up a really nice docking station by using the Touchstone as a stand/charger and then using the microUSB slot for peripherals like a USB keyboard and mouse connected to a hub with spare ports for flash drives, etc.
(Added September 7th)
Insufficient Available Bus Power Fix:
If you get this error, I haven't yet, some users have had success using this app posted on Rootzwiki.
I didn't feel like buying anything and already had some things laying around so I modified an Adafruit MintyBoost to accept a device via usb, add power, and continue on down the line...
Really all I did was solder a usb cable onto the female USB port on the MintyBoost, drill a hole on the other side of the tin and feed it out. The card reader conveniently fits inside of the mint tin so it's a pretty compact package.
The only down side I've noticed is that it also charges the TouchPad (the batteries will die quicker) and continues to send power to the card reader after the OTG cable has been unplugged from the TouchPad.
Excuse the crappy pic. I really don't feel like taking a better one.
I could never get the OTG cable to charge the Touchpad, I always thought when the Touchpad sensed OTG (grounding on pin 4) it refused to take power. You can disconnect the +5v Vcc to the Touchpad (red wire) on your OTG cable and OTG devices will still work.

I came to the same conclusion some days ago ,touch pad can't be charged using org cable,needs a regular micro USB cable and the barrel AC charger.I did many tests but having otg devices working and really charge at the same time its not possible,it seems like charging but its not.
Today I accidentally found this http://direct.sanwa.co.jp/ItemPage/400-GADR002W that by first look it could be awesome...

If its provides its own 5v power it would likely work, but I don't really see anywhere for an external power connection and it looks too small to house a battery.

For whatever reason, when I tried that the card reader wouldn't initialize. Once I connected the +5v from the OTG it'd light right up...
After it lit up I could disconnect the +5v and it'd stop the "charging" notification on the touchpad and keep working.

Then it should work fine as the Touchpad uses a standard OTG pinout, it just doesn't provide power so if it has a way to provide power to devices than I see no reason why it wouldn't work.
quick question that i didn't see answered above :S can i use the otg cable adapter without another power source (like can touchpad power it?)? Saw it asked above but didn't see anyone saying that the power source is required :S
kind of want to plug a usb flash drive into touchpad so I can type documents when I'm on the go and switch to computer. don't want to carry another power source either :S

No, the Touchpad doesn't provide any power for OTG devices which is why you need to supply it power. The cheap USB charger I linked to in the original post will work fine for a portable power supply if you don't want to build something yourself.
And it also appears you can't just plug the other USB into the wall?

Nice and cheap and the best part it works.
USB Hub works...sort of.
I tried this with a cheap USB hub I bought. I had bought it for my laptop and made sure it had it's own power supply to keep the load off my laptop, so I thought it would be perfect for this. Nice try though.
Turns out it needs 5V from the host to activate as well as the additional external power supply. Just fired it up with my TouchPad connected via a Y-Cable and my Laptop providing the 5V to fire it up. Works like a charm.
As yet to find out if it works with my travel charger providing the 5V and no external power supply plugged in, and how many devices I can hook up. It's got 7 ports so I suppose the supply might be useful then, but do I really need to hook up that many devices? Otherwise...pointless. Back to the drawing board I go.

Hi,
I have a wifi only htc flyer and would like to check if anyone has been able to get a usb 3g stick running on their htc flyer?
Thanks,
Kim
Not 100% positive, but the answer is most likely no. Some time ago, i bought an adapter to plug my flash drive in. After a bit of research, it seems the flyer doesn't give off enough power to the usb port, therefore can't power a device attached to it. There might be a way to do it, not sure though.
Hope this helps

USB Host is supported! You have to use an external powered USB hub though and then connect everything to it. I have pictures of how I found it works here:

So all we need is drivers and 3G support
I know that HC 3.1 supported USB hosts, but like i said, the flyer can't power the device by itself, you need an external power source, thats kind of an effort when you not at home. But good find

? My USB Hub is powered from my PSP charger! The Hub takes 5V and uses the same plug as the PSP.. I have an Idea! It's not Ideal but... Connect the USB Hub to the power pack with the PSP cable, Connect the Hub to the Flyer using a Mini USB cable and a USB Host cable! Et voila, Portable powered hub
I am also interested in this. As an experiment,I have ordered a cheap 3g router. One of the big questions is if it will support any of my usb modems.

I bought a usb 3g stick with the acompanying sim card, just put the sim into the flyer and am browsing the web no problems. U dont need the stick, unless ur flzer is wifi only

I'm looking to be able to use my external HDD (1TB WD passport) on my phone via OTG. As I understand, ntfs support varies with kernels etc but I'll cross that bridge when I come to it as I think there's a more fundamental problem.
I've got an OTG cable, and my mouse, usb pen drive, keyboard etc work with it. The HDD doesn't, because the phone can't provide enough power to operate the thing. I thought I could get around this by connecting it via my usb hub (which runs off external mains power) but when I connected this up to the phone and plugged the HDD in nothing happened. Likewise, the mouse and pen drive etc could also not be recognised by the phone when they were each plugged in via the hub (one at a time, I wasn't trying to run 8 things at once!) even though they worked perfectly when the phone itself was powering them when they were directly plugged into the OTG cable (if that makes any sense).
So, assuming it was a problem with the hub, I instead tried the method in this thread http://forum.xda-developers.com/showthread.php?t=1828032 and made my own y type cable so that now rather than the phone providing power to the OTG peripheral, the power now comes from a standard USB phone charger. I'm fairly confident that I did all the soldering correctly and there weren't any short circuits.
When I tried using this, I had the same issue as with the hub. None of the mouse, the pen drive etc could be recognised with the modified OTG cable, which was odd as physically nothing had changed from the point of view of the peripheral plugged into the OTG (the data cables connecting it to the phone were unchanged, and it was still getting 5V power, just from the wall rather than my phone) which makes me think perhaps the problem is a software one where the phone only recognises a USB peripheral/begins USB host mode if the peripheral is actually draining power, since the power leads running from the phone side of the OTG cable are now just an open circuit.
Just to confirm I hadn't just snipped a data cable by accident when modifying the OTG cable, I re-soldered the OTG cable to how it originally was and it worked the same way it had previously. This means all the data cables are still intact, so I think it must be a software issue.
I thought maybe a way of testing this would be to modify the y cable and connect the red and black power cables coming out of the phone to each other via a fairly hefty resistor (so you still get power flowing from the phone even though the USB peripheral is powered by the wall). But it seems a bit dangerous!
Has anyone else had trouble with this? I've read around on forums and for a lot of people USB hubs and y type OTG cables seem to "just work", although I've not seen anyone with an i9300 reporting success. I'm running the latest version of liquidsmooth, but have also tested on CM10.1 and have the same problem. It might be an AOSP thing that stock samsung firmware will fix?
Let me know your experiences!
TLDR: I'm pretty sure I've got a software issue where my i9300 only recognises a USB peripheral/begins USB host mode via OTG if the peripheral is actually draining the phone's power, and so doesn't work when a USB hub or externally powered (y type) OTG cable is being used.
Thank you!
It apparently only supports 500GB regardless of power source

Really? That's odd - is that an android limitation or samsung? Either way it still seems weird that my y cable/hub didn't work for the mouse/keyboard, is that something you'd expect?
Sorry I didn't read that part.
I have a portable passive hub. Kb and mouse working fine...
