Is there any possibility to charge my tablet via micro usb?does Uruk-Droid have this option?is there any hack to make it possible?I'm going on a trip with the car for a few days and i thought i could charge the tablet with a car charger with usb output but i've seen that with micro usb cable via PC doesn't charge so...
No there is no way to archive that.
But there are usb to 3mm cable.
But what has this to do with development?

no you didn't understand my question.i have a car charger via usb like the one from the photo attached but the thing is i think it wont charge with the car charger + micro usb cable because it doesn't charge with the micro usb cable not even when it's plugged on PC, and i think that it doesn't do this because of the software limitations look at other devices from Archos or other brands
No, you didn't understand the answer.
There is no possibility to use the Micro USB for charging, PERIOT.
http://www.newmp3technology.com/adc101.htm
This would work.
Thread moved to proper forum.
No its not possible
(i hate this so much)
Is there any adapter for usb car charger that goes to the hole for charging of the Archos?
Have you even looked into the link i posted?

hey!
i got myself a used TG01 but it didnt came with a usb host cable, so i decided to use a gender changer and the data cable to connect the peripherals to my phone, but it did not work...it does not recognize anything, am i doing something wrong ? or cant it be connected with anything else then the usb host cable provided?
thanks!!

it's a generic micro USB cable, you can find it at NOkia or HTC store
thanks for the reply, i already made some research and found out that the host cable is in fact a special cable that has 2 wires grounded on the micro usb side.
i actually was able to make one, but it must have broke a soldering point and if i connect it, it drains my battery in 10 minutes...
after the failure i just brought one out of ebay.
regards!
BTW: i encountered and other problem...
i had 2 micro USB cables, and i destroyed 1 to make the host cable, they looked the same so i picked one at random, now the phone wont change with this cable with the ac adapter connected i have to connect it to the PC to that it can receive power.
I tested with an other cable and it worked...has anyone experienced this?
I made one using an old USB extension cable. It took about 10 mins. Short the green and white wires on the female side of the USB cable. Now will use any normal in-car charger.

you have to have a short on the 2 data wires for it to charge.
Hi together,
ive asked me if it is possible to use an adapter for 1x micro usb (plug) -> 2x micro usb (jack).
Could the phone handle 2 USB devices at the same time?
Maybe then it is possible to use the HDMI output and the USB host parallel?
For example to use an TV as screen and an HDD as the source for a movie.
This would be nice.
Thanks in advance.
macc
When the connector is used for HDMI I doubt it can be used as USB at the same time, I'n sorry.
Maybe in a few months cyanogenmod provides a hack, if there will be an dual adapter soon.
We will see. Thank you.
macc
The hardware needs to allow this if it'd become possible. You need a really smart USB dongle that knows how to split the HDMI output from the USB output.
Sounds a little too difficult to ever happen.
Hmm thats right. I think i still dream xD
But thank you.

it is not possible. because as stated on this forum many times before, the type of usb connection is determined by the resistor between pin 4 and 5 of the micro usb connector. the strength can tell the phone, that there is either a charger, a pc connection, car kit, jig, usb otg or mhl connection present.
and i believe, this is an important thing to keep in mind for so many things:
for instance, why the original car kit triggers car mode and generic car charging cables don't or why not just any micro usb male to usb a female will work as a otg cable or why flashing should be done with the original usb cable...
so if you were to buy or build a micro usb hub, since it has no resistor in the very plug that connects to the phone, it cannot be used for anything but charging and quite frankly, i wouldn't connect more than one charger to the phone.
however, if you want to use your phone for presentations or watching movies and still be able to use it, get a bluetooth keyboard and mouse or a bluetooth presenter or do it the other way around and use a usb input device and transfer your media using allshare. everything else is physically impossible, so neither CM nor XDA can do anything about it. the only device that can do what you want is the new motorola. it has a separate micro usb and micro hdmi port and a docking station, so you can use it as a full notebook.
Thats obvious. Thank you.

Is there any way to connect a USB Host adapter + charge the TF at the same time? I'd like to be able to watch videos (most of which are on my USB HDD) without having to spend hours copying them all to MicroSD just so I can charge the TF (and I use it a lot in my car (while parked, not while driving obviously) and dont want to have to dock the TF to do so (the main reason I use a tablet in the car is there is so little space between me and the steering wheel))
Possibly dissecting a Datacable so it forks the charge into 1 plug and the USB into the other? or wiring in a barrel plug to one of the USB host adapters? (I'm assuming it's not possible to just use a generic USB hub and somehow reverse the power on one of the ports to allow charging...?)
Not sure if his answers your question, but essentially, the pin layout on the cable that connects to the wall charger for the Asus Transformer matches the USB 3.0 spec.
As seen here on Amazon, you'll need a USB 3.0 cable to effectively work as an extension cable for charging via the wall-outlet.
Therefore, by the same logic, if you have a USB 3.0 port on your computer, you'll be able to make use of the extra voltage to do the same thing.

I don't think the USB 3.0 on a computer will supply more than 5V and 900mA. Not enough to charger the TF.
You best bet is to use a USB 2.0 extension cord, take out the wires that go to pin 1 and pin 4 and connect those wires to a 12V power source.
Absolutely no need to use a USB 3.0 extension cord.
Look here: http://forum.xda-developers.com/showthread.php?t=1087321
To answer OP's question, there's only 1 USB host port on the ASUS Transformer TF101 USB Kit. I don't think that's possible.
Confirm both replies - the Amazon-linked cable does indeed allow an extension of the power delivery from a stock power adapter, but connecting to USB 3.0 port on a PC will not charge the device. Just connected it direct too, not via a hub (even though it is a 3.0 hub - didn't work on that either...)
Suspect custom wiring required, as OP has speculated - anyone?
I made a USB dongle that plugs into the USB port on the touchpad and provides a powered female USB-A port. It is basically a portable USB charger/battery with an OTG cable soldered to the USB port. Attached is a quick pdf showing the process. It's much smaller and more portable than using a y-cable and powered hub or battery pack.
The charger is $13 on Amazon with free prime shipping and OTG cables around $2 on ebay.
It's nice because it's small and I can secure it to the my case with a rubber band, providing a quick connection to a keyboard/mouse or usb flash drive. The particular charger charges via any powered USB port with a provided cable.
This is the battery pack I ordered, note the picture on the amazon page is not 100% accurate:
http://www.amazon.com/T-Mobile-Port..._1_1?s=wireless&ie=UTF8&qid=1325984238&sr=1-1
This is the cable I purchased, there are cheaper ones, but they ship from China:

Would that be powerful enough to power external portable hard drive like WD Passport?

Unfortunately, I don't have the power specs on the battery pack. If I come across a USB-powered hard drive, I'll test it.

that looks nice.. but you re saying that its plug and play?..
you dont have to mount/unmount?
why didnt you get one w/ more usb ports?
your pics are clear.
i wonder how easy it is to do the battery hub like yours but w/ 4 usb ports
Nicely done, very good solution and tutorial. again excellent!!!!

This hub has 4 ports, a battery plus solar charging. That said, if I buy it I'll probably just plug it directly into the OTG cable rather than solder them together. Then again my soldering can be a little rough.

Deserves sticky, love mods like this even if not always practical.
Cant believe they didnt give the touchpad a powered usb host. I guess they figured people would have issues with not enough power or drain the battery too quick with it.
So I think when I have some spare time I may mod your mod and show how to make a powered usb host that plugs into the wall charger so when your "docking" somewhere to charge you can hook up a keyboard and use it without restriction and even be charging the touchpad at the same time.
Probably don't even need to be too creative a proper Y cable may do the trick out the gate. Just to track one down.
Probably a stupid question, but it wouldn't be my first one...
Could you simply use a USB male-to-male cable to go between the battery pack and the OTG cable? Eliminate the soldering that way?
Or am I missing something?
I found a cable that I think will work perfectly for my idea of doing this from the charger instead of from battery: http://www.dealextreme.com/p/usb-fe...gb-tf-card-card-reader-kit-for-xtc-clip-82289
You can do it much cheaper with adapters and a regular y adapter though, and you may want to do so, so that you can have a longer cable from the charger to the y split, but yeah I will try this out sometime soon and let you know how it works.
The charger probably gives enough power to easily run things like a external HDD and such while the battery pack may not.
@Vicious ... couldn't that possibly put too much power to a USB device? Just saying since it is probably meant to be hooked up to a regular USB 5v port and (I don't know the specifics but) the touchpad USB power adapter has a high AMP output (might be talking sht here).
Nothing to worry about a device only "pulls" the amperage it needs so you can have extra with no harm to the device. It is the voltage that needs to match and usb is standard 5v.
Having too little amperage can actually cause a device harm due to malfunction, like a head crashing on a 2.5" hdd during use or a thumb drive failing to flash properly corrupting a sector.
I feel anybody that uses the touchpad in a docked setting that wants to use a keyboard may very well make use of my idea, that I of course got from the OP's idea.
I'll part it out for the cheapest way to make it without any cutting/soldering and test it soon enough.

That cable will work fine. I wasn't doing anything special, only eliminating the y-cable. I mainly wanted a small form factor way of adding a USB port to my case for portability. Now I can put a movie on a usb drive and watch it on the go.
You generally don't have to worry about using a supply that is to powerful. As long as the voltage output is 5 V, the device will only draw a certain current and consume the corresponding amount of power. The rating on a constant voltage supply is simply the maximum current it can provide, the amount it provides depends on the properties of the device.
Say you have a device, it states it operates at 5 V and draws 100 mA of current. That means the impedance of the device is R = V / I = 50 ohms. So if you use a 5 V supply rated to at least 100 mA, the device will only draw 100 mA. The supply can be rated for 100 mA or 1000 amps, it does not matter. (Although you wouldn't want to use 1000 A source as if something breaks or shorts it can draw a higher current)
Wikipedia "ohms law" if you are not familiar.
I tried to do this but can't get it to work, the touchpad shows the charging battery icon only it's not charging, and running dmesg it say source=charger mA=100 and usb otg exited low power mode and then right after says it entered low power mode... Not sure what the issue is...
edit: I'm thinking it may be my soldering work, gonna give it another pass...

You may have the two data pins shorted together. To the best of my knowledge, this tells the touchpad to go into charging mode. The touchpad charger does this, because in order to charge, it must draw more power than USB ports are designed to provide.
You need to remove the two resistors circled in the PDF. These keep the data pins shorted together as well.
This is a really great idea I think I might try it and your tut is very well explained thanks for taking the time out to put it all together
Thanks
Mouse works fine, keyboard hasn't been tried yet. How do you access a flash drive through this? What are the steps?
If you just cut out the resistors in the battery hub, could you just use the TP's regular cable to plug into one of the ports on the hub?

Good Morning
When I want to connect my droid X phone to my laptop, the cable is usb on one end and micro usb on the other end. So can I use that on my Sony S also to connect to the laptop? or are there different wires inside the cable or something so that I cannot use it, different wattage or amperage or whatever??
As always I am technically challenged LOL
Sandy
The Sony Tablet S uses the standard Micro-USB cable so you'll be able to connect to your laptop with no problems.
It will work for both, given the chip( Mini USB) is the same for both. The cable just carries the current. It is the charger portion that puts out the specific voltages. You are good to go as long as the mini USB fits

Really? This works?
Uh oh. I've tried hooking up my tablet to the PC with a standard micro usb cable. And also with the sony converter that makes it a normal sized USB port and a double ended USB cable. Both of these didn't do anything for me. I've just been transferring files to/from it with the sony converter and a jump drive.
Anyways, let me know if everyone else is normally hooking the tablet to a PC or if you guys are just assuming. Thanks

You should only need the one cable.. The cable I use for my HTC Desire HD works on the tablet and the same with the cable for the Galaxy S II as they are the same kind of cable.

Same here. I plug it in with a cheap USB <-> Micro-USB cable and it recognises it instantly and I can copy stuff to and from without even having to mount the storage manually.
Weird!! I tried plugging it in with my normal phone's micro usb cable when I first bought it and nothing happened. I tried again last night and nothing happened.
I just read all your posts about how it will work and I tried again, and my computer recognized it this time.
