[Q] HP Touchpad OTG support?

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

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.

Any Roms that support usb otg

Are there any Roms that support usb otg.
I'm on clean rom 2.5 and can't get it to work. Also the few Roms I have tried it hasn't worked.
Sent from my SCH-I535 using xda app-developers app

CleanRom 2.5 (and 2.1 before that) and it works fine for me. Higher-drain usb devices might need their own power source.

What kind of usb otg are you using maybe I have the wrong cord. Did you have to enable any options?

I used what I thought was a non-OTG micro-usb-to-usb adapter, and then a cheapo OTG cable and both worked with a wired Xbox 360 controller. The cable also worked with a flash drive. I haven't really tried any other devices.
The ones I used were:
http://www.amazon.com/T-Flash-Adapt...UTF8&qid=1350406382&sr=8-1&keywords=otg+cable
and something like this:
http://www.amazon.com/SANOXY-Micro-Male-Female-Adapter/dp/B0027YYMU6/ref=pd_sim_cps_8
I didn't enable/disable anything when I did the tests -- it just worked. Possibly I had done something earlier, but I can't remember anything specific, and haven't done any specialized hacks for this.

Yeah I have the same cord odd. Oh well .
Thank you for taking the time to supply the links.

Is it possible to attach a powered hub to
A) Attach higher power-requirement devices that do not have external power
and/or
B) Attach multiple devices for simultaneous use (say, a keyboard and a mouse
??
(my USB OTG cables are in the mail)

I *believe* both answers are "yes". You can attach a usb hub. A powered one should give power to the devices, or you could try a "y" usb cable to provide power as well.
btw, here's a video showing off some of the capabilities (i believe this is the international version):

Shoot. I guess I'm not sure what else to try so hopefully someone else can chime in. I haven't tested it out recently, but I'll let you know if I happen to discover anything.

Works fine for me...just plug the otg cable in (I had one from my old fascinate I got off Amazon for like 3 dollars...and I can either plug a single item like a mouse or flash drive straight into it or a hub that can be powered or not...if you plan on using an external hard drive is suggest plugging it in...I believe the phone holds up to like 6usb connections at once but don't quite me on the exact number...I have had a mouse, keyboard, flash drive, sd card reader, and second phone all plugged in at once...only think I've found is that not all usb hubs will work for some reason...I use a 30 dollar (at bestbuy) belkin 6 port hub and never had a problem...to have it powered though you have to plug the actual power cable on the hub into a power source and run a usb cable from the hub to otg cable...as far as I know every room should support this...I used liquid smooth which is an aosp rom and it works great, also works great on any tw Rom as the capability is built into the phone...hope this helps anyone with questions about this...only think I haven't tried is a hard drive mainly because I have no need to buy one but it should work...and if it means anything I use all 2.0 cables and accessories, no 3.0 or 1.0

[Q] Help with USB Host (OTG)

Hi All,
I'm trying to get a USB device connected to my phone (specifically an OBDII reader with Torque Pro). No matter what I do, I can't get it to recognize on my Nexus S 4g. When I run USB Host Diagnostics, it basically says it can't find anything.
I'm running a flavor of Cyanogen 10 with its stock kernal.
My questions are:
Do I need to go through a powered USB hub to get the proper power?
Do I need a specific kernel with the correct host modules enabled? (if so, can someone point me to one)
Thanks,

Torque Pro worked fine with my NS4G with a cheap ebay bluetooth adapter with no hassle. That adapter had no batteries at all, it was powered through the ALDL port on the car. I couldn't imagine needing power since no scanner I know of needs power at the ALDL port, it pulls it from the port itself. I would bet it is USB driver problems, or problems reading the USB adapter through Jellybean because of this new MTP protocol that sucks

Good to know.
Should I try a HoneyComb ROM? I guess it COULD be the OTG cable I got from amazon. Maybe it's not plugging in all the way.
thx

No Honeycomb roms for Nexus S...
I highly suggest a OBDII bluetooth adapter. They're 15$ on the net and will spare you the trouble. Make sure you find one that has good reviews, some cheap ones have problem connecting to some cars because of broken J1850 PWM (i think it's PWM, might be VPW) protocol.

Smallest Micro USB to HOST/CHARGE adapter?

Hi guys
What are you using to power your Tab S and have a hard drive etc connected
at the same time?
Looking for the smallest possible option to limit bulkiness
Thanks!!

what about this cable.
http://www.amazon.co.uk/dp/B00EJP5X...m=A3P5ROKL5A1OLE&pf_rd_r=0RE8386SWCWM00V7XPZJ
John.

Yeah looks good....what cables are you guys using for charging and host at the same time?
I heard its not recommended to use an external hard drive without supplying power to the Tab S

Yeah, your right about using an external power supply when using an portable hdd with your tablet as it uses too much power by the hdd, the cable i linked above has an microusb socket for you to plug your tablet usb power adaptor into.
John.

The Y-OTG cables supply power to the OTG device (e.g. SD card USB reader) but not concurrently to the Tab S. Basically all they do is reduce power drain on the TabS. The previous comment to try to use a powered USB hub or a self powered USB device is good advise.

I have to resist the urge to go cheap on power adapters, after i had an car and an mains adapter start smoking in a week and nearly blew-up my HTC M7, I have been looking at the Belkin USB Adapter 2.4amp it comes with an 25.000 damage warranty, they cost between 15-20£ in the UK.

Have you tried the ones on aliexpress.com??
They say its otg and charges at the same time

Samsung tablets no longer supports this function that I know of. They used to have a dock mode that would do usb host charge and hdmi out ending with note 8. I tried all types of resistors and cables so far the lava adapter is the only one that worked. It's a solid 1amp charge with usb function. I wasted more money making and buying cables that said worked but never did. If u want ou cheap buy a usb host cable put a 1ohm to 10k potentiometer in between ground and Id pin turn it slow til u see usb host triggered on the tablet but again it could be a waste of money and not work. I had a tab pro trigger usb host and charge that way but was very unstable current. Any questions let me know.

Hi.
In the user manual it says that the touchscreen my act-up while it is used while the tablet is charging if the power supply is unstable.
A quick Google show this is an common issue for a lot of brands of tablet/phones

Otg support?

Hello all.
Just bought an otg but doesn't seems to work.
Also used the second otg I bought in case the one came out dead.
Does anyone had any similar problems?
My phone has Oreo out of the box.

Otg is supported pnly with the original adapter.

sorry for necroposting, but i have an otg cable and the original adapter, but the phone isnt recognizing the usb device at all. i have tried channging the usb connection options to MTP, PTP etc etc

You should not have to do anything to get OTG going. In particular you should not have to change USB connection type from developer settings manually, that should happen automatically depending on what device you connect.
The only catch is that you need a decent OTG cable, which has all the correct pins in it. Using a microUSB OTG cable + an microUSB to USB-C adapter for example will NOT work (not unless the microUSB adapter has the OTG pins, which is really unlikely).
I'm using this Anker OTG cable and it works perfectly, first try. So far I've tried external storage devices (card reader, stick, even a 2.5" HDD enclosure), keyboard, mouse, and a MIDI keyboard.
If you need an app for accessing USB storage files I can recommend either USB Media Explorer, or the USB OTG plugin for Solid Explorer.
