make sure your usb extension is usb 3.0 compatible. The transformer uses the extra pins for extra power.

So simple question, does anyone know (have tasted) if Touchpad supports OTG like for example Galaxy S2?
I bought these from DX: http://www.dealextreme.com/p/micro-usb-on-the-go-host-otg-adapter-pair-50774 and is working great with my Galaxy S2, but can it be used for Touchpad?
First, it is TESTED.
Second, Nope no native support yet, might have to wait till android port is complete, might take a couple of months.
[Q] USB OTG?
That's pretty cool, keep up the work.
Does anyone have ubuntu chrooted to check if the usb module is reporting anything?
kinda pre emptively ordered one in hope.

Apparemtly there is built-in OTG USB support using a powered hub or Y cable, and an OTG mini-male to regular female USB adapter, according to rootzwiki.com/showthread.php?4332-Functional-USB-Host-on-Touchpad

One of those newbs who can't post links eh? I'll fix that...

The Touchpad doesn't have a powered port is the only problem - so provide power to whatever device and you're good to go.
what about a external HDD with its own powe supply, will it work..
unfortunately, i'm still waiting for my TP so cant test
Does it work with your HD2?
If so, there is no reason not to work with TP
(Hint: HD2 has same kind of usb host capabilities that needs external power supply)
So was it ever established whether or not USB OTG works on the Touchpad? Sorry to necro-post, but I picked up a touchpad during the firesale, have been loving it with first WebOS then CM9, and since I ordered a USB OTG adapter for my GSIII (this friday!) I was curious if there was anything I needed to know about using OTG with the HPTP.
It just works with a powered adapter. Nothing more to it then that. I've plugged almost everything into mine!

Thanks for the links, will see if I can get the needed cables etc from eBay/Amazon
Thanks for the help. My OTG cable and other things from Monoprice should've come yesterday, so hopefully I'll have them tomorrow. By powered adapter, do you mean something like a powered USB hub? Although I didn't get that OTG cable for the touchpad, it'd be a nice treat to be able to use it with that, it would definitely make moving movies around a lot easier.
EDIT (10/19): Dangit, they didn't come today. I'll have to see what's up, because they've been in my area for a while according to tracking just not coming.
Yes, u will have to use either a powered USB hub or get power from a USB charger that doesn't have the data +/- pins shorted internally (purchased or modified). If u plug device (ie phone) into charger and it says "ac charging" that means the data pins are shorted.

hi:
thread speaks of wiring directly the 5v stepup to the existing microusb port w/ diode..this would be great to see.
i am notsmart but w/ detailed instructions AND pics and supplies links, i would consider trying it.

Alright, thanks. I think I need to get a powered hub for my laptop (which I am currently using as a desktop with external monitor and keyboard) so I there may be a happy coincidence here.
Also, just checked on my touchpad, and the HP charger says charging (AC) as well as my phone charger, which I think started life destined for some Blackberry.
The powered hub should work though, and that would make a great machine for typing and working in bed as opposed to my laptop burning my thighs off.

I just verified that if you get the Micro USB Host OTG Cable With USB power ($6 from AppleCable on Ebay) that Ramjet73 mentioned (or this one), it will work with any standard USB charger (ie the 1 Amp HTC or 2 Amp HP Touchpad Charger) because the USB Power Connector is Isolated. I also picked up Applecable's USB 2.0 3 Port Hub with data Sync Charger cable for $7 (I may try to modify it to be a USB OTG powered hub with this).
I will be updating the OTG thread I mentioned earlier. See attached:
I've never successfully used OTG. I've bought 2 cables.

I've received a bad one before. Cut it open to verify the id pin hadn't been tied to ground like it was supposed to be. I can verify that OTG is enabled with the CM9 Nightly and jcsullin's latest Cm10.

I was wondering if there is any such device / cord which would convert the Asus proprietary plug on the transformer to a USB cord or something so I could plug in different things without having to buy the keyboard....
Yes it does exist:http://www.asus.com/Peripherals_Accessories/Eee_Pad_Accessories/External_USB_Adapter/
Could you charge the tablet with a regular USB cable using that adapter?
Only when in deep sleep or turned off - but it charges.

No because the USB adapter linked only outputs 5v on the USB port, its not an input.
The USB socket is the wrong type for normal USB cables used for charging, but even a USB-A to USB-A adapter wont allow charging and may even destroy the USB adapter (well, it might not, but I certanly wouldnt want to try it!)
That is sort of what i was afraid of. I was hoping that since I can use the propietary cable, I would be able to switch to a longer cable with the help of the adapter.

Just attach an usb3.0 cable to the propietary cable. Then you have a longer cable.
I'am using this with the tablet and charger.
It has to be USB 3.0 cable? Dang, I actually do have an older extension cable somewhere (forgot all about it until I read your post) but it is pre-3.0, but hey, if i find it I will at least give it a try, not like something would brake, right? Right??
hmm...I had asked this in my thread, but no one has given me a straight answer. Looks like it wouldn't work even with Male A to Male A. I already bought one, so maybe I'll give it a try. Has anyone done so before?

Yes, it must be a usb 3.0 cable.
I have this one and can charge the tablet with this cable attached to the propietary cable and the asus charger
Just tried it again and it is now charging.
That is cool, but I was hoping it would be in a "cord" form because imagine you would have that sticking out from your device, then on top of that you would have your usb plug sticking out as well...
Also, would this work with something like a wireless keyboard and mouse? (the wireless receiver is USB)...
Hi all
This is probably a really obvious question, but here goes.
I have a Xoom.
I have a HTC Desire S phone.
I want to USB Cable Tether my HTC Desire S to the Xoom
I already have 1 x USB OTG Mini-USB Male to Female USB cable connected to the Xoom.
So ..... to correctly OTG connect to the HTC Desire S to the Xoom:-
=> does the lead going from my phone to the Xoom Female OTG USB cable also need to be OTG ?
or
=> can the lead going from my phone to the Xoom be a standard NON-OTG cable ?
Thanks,
Ben

Hi llama-power
Wow ...... I had *assumed* that the cable running between the 2 devices had to be fully / completley OTG compatible.
So basically, as long as the cable hanging out of the Xoom is OTG compatible, then I can use a stock standard NON-OTG cable to run from it into the phone ?

If you plug your OTG-cable into your xoom, it (the xoom) will behave like a regular pc. Thus, whatever you plug into that OTG-cable can be as stock as it gets...
Hi llama-power
Huge thanks - first time I've had it explained so easily and simply that I understood it clearly.
Very much appreciated and all the best,

as a side note it should charge your phone up too! so you only need one charger to carry round (The Xoom)! XD

But not at the current that your dedicated charger would supply, thus you'd have to charge a LOT longer...

Hello!
Is possible use a converter USB female-female with normal asus tf101 cable?
I mean ad adapter like this
I know that exist the official asus usb adapter, but is too big ...and expensive!
Thanks for reply!
No, completely different pins are used. And theres no power going from the tablet in the original data cable.
Theres a reason the adapter is so big, it contains voltage regulators, fuses etc.
edit: next time do a search :/
I'm sorry if this has been asked before. I tried searching but nothing came up.
Is there any way to charge a Galaxy Note 10.1 NT-8020 AND synch the data at the same time via a USB port? Right now I use the stock charger and cable together with MyPhoneExplorer (Android app) to synch the data via Wi-Fi.
I know if I use the original Sammy cable plugged into a USB port on a desktop PC, I can synch the data but only charge if I switch off the device. I assume this is because there's not enough current available for charging from the USB port. But is there something different about the cable itself?
If it's just a case of insufficient current, I should be able to charge/synch via a powered USB hub but the one I tried just now doesn't work either. If it's just a question of buying the right type of powered hub, then can anyone suggest make and model?
Thanks in advance.

Thanks. That's what I was hoping so might risk buying a hub I saw that claims to deliver 2A to the USB ports. I tried an old 10-way USB hub that has a 2A PSU but this can't charge the Note while it's switched on so obviously it's not supplying enough current to the ports. I kinda imagined it would deliver 2A to one port or 200Ma to all 10 or something like that..

EDIT
Rats! Just found out this product is a charger only ie no data ports so that's no good. There must be some technical reason why an external, powered USB data port hub can't be made to deliver 2A or so.
