Not one to relax and enjoy the spoils of war after conquering the Wall/Car charger mystery I have decided to move on to the subject of USB host without the dock. Sorry if I am duplicating other similar threads but starting a new thread helps me through the process of testing. I'm hoping the asus USB host adapter will be out soon so I can gut it like tuna but till then it is back to the rig I used for the charger probing.
Update 10/16/2011
So what we actually now know.
1. USB host mode requires a board found in the USB Host adapter from Asus
2. Some users are having issues with the adapter staying connected. Bad design IMO, too big of a device to be hanging off the tablet connected to thumb drives and other devices.
3. 5V is being supplied to usb devices, I have not personally verified this but will soon.
Some options
1. Build USB Host "Dongle" with connector and USB adapter.
Sounds like people are having disconnection issues, a dongle might be a better solution for that taking the pressure off the connector on the TF and move it down a wire to dongle connector. This will be my first build since it shouldn't be to difficult.
2. Machine a small attachable dock that sits at the bottom of the TF which contains the host adapter, memory cart reader slots and USB ports.
I love this idea but will take time and money I don't have at the moment. BUT drawings are already done and I'm having my machinist put it on his to do list at the bottom. Prototype in 45 days but no promises.
3. Modding a TF to contain the host adapter internally.
This requires you to open up your TF and install the board and a connector. A daunting task for anyone with even good circuit board and fabrication skills. Best person for this job is Bob, but is there space in the case?

First Mod, Host Adapter dongle.
While building this on I'll looking in to the capability of charging the TF while using the host adapter.
USB adapter shows up tomorrow and I hit the ground running. Pics and updates to come. Stay tuned!
Hey,
Any updates on this? I would love to see a solution to connect USB devices without needing a dock.
Waiting for the official adaptor might take a while: Asus Australia confirmed that the adaptor is not coming any time soon (and maybe never to AUS at all), Asus Germany can't give a specific date.

So what do we know
1. Connecting a USB 2.0 female to female coupler using the factor sync/charge cable from the Table to other USB devices does not work.
2. Asus will be releasing an adapter that allows for USB host features and this tells us it can be done.
3. Asus used some of the usb 3.0 pins to show termination from the tablet to start charging at 15V so this method might be in practice for the usb host function.
I've done a little monitoring of data pins on the factory cable but see no difference between when a device is and is not connected. I have a feeling we are dealing with 2 things, 5v power from the tablet to power the usb device and a pin termination to trigger the host function.

Following the OP's logic..
I do not believe that a Female to Female USB3 would be enough. I suspect and trying to locate one is a pain that you will need not only a USB3 AF to AF but also a USB3 Powered Hub (or USB 3 Powered Device) as the TF cable does not supply power..
I tried the USB 2 AF to AF path with my powered hub and can confirm it does not work, TF will mount fine on PC via the HUB so it is not a connection problem so I suspect like the OP that we need all the magic pins of a USB3 connection which logically would also mean we all the magic of a USB3 hub (or device) as well..
I cannot find a USB3 AF to Micro AF cable anyplace (They are all male) so even if I can get my hands on a USB3 powered hub (which are also rare) I could not complete this experiment..
I suspect the lack of the OP's postings would also indicate they are having the same trouble as well..
So in summary, I strongly believe we need USB3 Powered Hub + USB 3 Cable from the Hub to the TF Cable
Anyone got those?
Well I done some searching and found these two that should provide all the right specifications for the TF but I am starting to have some significant doubts that this is all worth it considering this is only a theoretical solution based on USB3 pins logic vs just pay the $149 price tag and get the keyboard dock that we know will work..

As I posted in the other usb host thread, the USB adaptor is listed in a German online shop: http://forum.xda-developers.com/showthread.php?t=1103784
I just want to know when that damn Asus USB dongle is releasing. I don't need the keyboard dock. Already have a 13.3 laptop.
the same site has also in stock the sd adapter (nice for my photo machine, avail at 19€ as well), and the minidock (2 usb + stand) at 29€.
The sleeve is avail at 34.90€, the vga cable at 29€, and a travel kit at 39€.
Everithing is said being available in 2-4 days...
Last week was baja 500 prep for my but i'm back and moving forward with testing.
Don't waste your time with the female 3.0 adapter. The tablet is using one of the 40 pins on the proprietary adapter to look for termination from the keyboard dock to activate the USB host function. This is my theory but I still will test all 9 of the 3.0 pins.
The only way I will be able to test all 40 pins on the tablet connector is to either find a bare connector or wait for the asus usb adapter and open it. I'll start lookng for a bare connector next Week

So no new solutions for hosting on the TF? No new information about the adapter?
Hello guys,
Does anyone try this:

Nothing yet on either. The adapter from Asus has not shown up anywhere and I'm still in testing mode for a DIY solution.

I don't see a reason why that won't work but my focus is to activate the host function so that USB devices will be recognized and accessible.

Thanks DevCake looking forward to seeing some more results.. I would not be surprised if your theory is correct.. I not gone down the Female adapter path yet until we can verify exactly why USB Host is not being enabled..

The adapter has shown up in a German online shop (cyberport.de, search for "usb extension kit" or "sd extension kit") and is listed as in Stock. I wrote them an email to get confirmation that they really have it in Stock and shippable. Maybe somebody in Germany can make a teardown and show us the internals!

If you google "1D09-36X" it comes up with other EU sites that carry it. Hopefully it won't be long till we get it in the US.
Does anyone happen to know the type/model/name of the connector is.
Maybe we can find something that is the same pin config and cut it open and splice in a usb 3.0 female cable.
I've spliced many a cable together for similar purposes, just need the connector end.
We as reseller have direct contact with asus. I called today Asus Netherlands about the usb host adapter.
Atm this moment there only 2 accessoires on the market, which are as follow:
- Asus Sleeve
- Asus Dock
The Sales Manager at Asus Netherlands told me that several other people asked for the USB Host adapter also. They said it wont be on the market until 3th quarter of the year (Aug/Sept/Oct).
Asus Taiwain puts these items on the market. Asus Taiwan understands that there is some demand for this USB Adapter.
So, we have to wait until 3th qaurter 2011 or try to fabricate something ourselfs or wait for some crazy chinese which puts something similiar on the market.
Can EEE PAD Transformer support Full USB HOST functionality using stock connector provided by ASUS using something like below FEMALE TO FEMALE USB Adaptor ?
http://www.hkcolordigital.com/usb-2.0-a-female-to-usb-2.0-a-female-adapter.html
I know ASUS dock keyboard do have USB port and also, ASUS is selling USB adaptor for around $45, but I do not want to spend that much.
Since ASUS stock connector which is used for charging as well as data transfer from PC support USB functionality, I believe it should be easy to implement.
Any suggestion/solution ?
Thanks
No, it wouldn't work.

I can't find pinout for ASUS charging connector, but i think it has USB-host pins in it - so you should just solder an USB-female to them in right order.

this might work. USB OTG is what we looking for
USB Adapter Coupler Type A Female to Female
I have ordered "USB Adapter Coupler Type A Female to Female" from ebay ($3 including shipping):
http://www.ebay.in/itm/120868617077?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649#ht_932wt_1143
Once it reaches to me, I'll try what is possible with it.
I received the "USB Adapter Coupler Type A Female to Female" today and tried to connect USB pen drive and as it was expected, NOTHING HAPPENED.
But, I still think it is possible. I have seen Nexus and Galaxy phones with USB host online.
I think, to be precise, it is not only Female to Female adaptor to be connected to stock connector, but it needs some power (+5v) as well. For this, I think it need USB Y Connector, as in attachment. Below is the link for reference:
http://htc-linux.org/wiki/index.php?title=Msm_Usb_Host
Now, I am thinking to open Female to Female USB connector and solder 2-wire with USB Male connector to it (I have extra USB mouse) for power (+5V & Ground) and try again.
look at last link in my previous reply. There are photos of disassembled host adapter and some schematics-pinouts. TF has USBhost, but it on different pins than usb-slave cable.
I am a user of HTC Flyer and I have done some research on connecting it with TV . I know that it is possible threw MHL adopter and HDMI cable. But what I am saying is that can it be possible threw RCA AV TV adapter Cable. I want to know that if it will support internally because physically I think it is possible. Here is how :-
1. First we will connect HTC Flyer threw OTG cable (Micro-USB to Standard USB Female cable).
2. Then we can connect OTG cable (Standard USB Female Port) to USB Male A to 3 RCA AV A/V TV adapter Cord Cable.
3. Then 3 RCA Port to A/V TV.
Has any body thought of it. Can it be possible. Please reply. I think this will change my way of using HTC Flyer if it is possible.
Please suggest.
i am not sure i get what you think is possible, but converting DIGITAL to ANALOG signals require a converter outside your flyer for this to be possible, so its not all cabling solutions you think you need here. the cable you think of is pure analog reception, and digital cables are pure 0 and 1's
Has anyone made an OTG cable for the TFP? I don't like the chunky USB OTG connector and thought an OTG cable would be much better.
Not quite sure what you mean.
The only proper usb connector is a standard type A connector located on the keyboard, it has insufficient pins to implement OTG. The only other usb connectors are the propriety asus ones, one on the tablet and one on the keyboard, the other small connector on the tablet is HDMI output
I have the "chunky" USB OTG connector as well.. I don't think there's a cable though... I looked everywhere on the net
I don't have a dock therefore the only way I can plug a USB flash drive, Keyboard/mouse into the TFT is via the ASUS USB OTG Host adapter View attachment 1384503
I was after something a little slimmer and believe a OTG cable would be ideal - Refer to picture for an example of what I'm referring to View attachment 1384504
Micro USB OTG cables can be used with many phones and tablets sporting a micro USB connector. The TFP obviously doesn't have a micro USB connector therefore I was hoping someone knew how to make an ASUS 40 pin to female Type-A plug which replicates the ASUS USB OTG Host adapter.
Has anyone pulled apart the ASUS USB OTG host apapter? What's inside it?
Hey guys. There are several articles and videos around on how to make your own OTG cable. It essentially involves shorting a single pin. I have no idea if it'll work with a TFP, but I'm going to give it a shot today or tomorrow if I get some time. My plan is to use the normal TFP USB cable, but plug it into a female/female USB gender changer that has been modified to short the pin. I'm almost positive that it'll work on my SGS3, and I don't see why it wouldn't also work for my TFP. I'll report back.
Nevermind. I now see that the TFP USB end has five pins, so they won't match up with the 4-pin female USB port. Oh well...
TFP and OTG
Does anyone know if the OTG will support a USB hub?

The TFP doesn't have OTG, it's a regular USB host.
So yea, it will support a hub because it's a standard USB device class, with its driver already part of the kernel.
I've successfully made an OTG cable. It works fine.
I have also rewrired my monoprice 11pin to 5pin MHL adapter directly to my MHL output with a 40.2Ohm resistor. The phone recognizes it as a smartdock and the MHL/charging is all working. I am running TW rooted...
However when I add the proper connections to another OTG adapter, I don't get any USB enumeration. I can post pics and pinouts if anyone cares..
Monoprice part of the 9-5 adapter is 9716... I can't post links yet.
Anyone have an idea of how or why USB enumeration isn't working? I get power to said USB device, but nothing shows up on the phone side that a USB device is connected or working... I verified the device with the original OTG cable I made, so I know the mouse works just fine there.
