[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.

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.

[Q] Is it mandatory to connect the charger with the HDTV Adapter ?

Hi Guys,
I've got my HDTV Adapter for a stock Galaxy Note 10.1, I'm a bit disappointed because it looks like it's mandatory to connect the charger (the cable already has got an extra slot for connecting the charger) in order to make the note send what it is displayed on its screen to the cable so I can see it on the computer screen for example.
Does anybody have an idea if this is true or not ? I'd love the idea if it is an option but not an obligation !!!!

My experience is yes, power is required. But this can be as easy as plugging in the usb to the tv or monitor if it has a usb port, you dont HAVE to use the charger

Which adaptor did you use?

Well, let me tell you why I'm a bit disappointed, I used to have an iPad which used in a lot of meetings moving here in and there with my pad and cable, now I've to have a power source around or even a computer, with a at least two cables with/without a charger, I'm not bothered with that at home but while one business this note didnn't prove to be a stand-alone, I'm not sure if an app that may simulate charging can deceicve tthe note on that aspect or not but so far, this can be considered a draw-back

[Q] Q: USING HDMI & USB peripheral ( ext HDD ) at the same time on Galaxy Tab 2 10.1

[Q] Q: USING HDMI & USB peripheral ( ext HDD ) at the same time on Galaxy Tab 2 10.1
Hi Guys,
Do not get me wrong, I have been searching online for the samsung adapter that would allow several simultaneous conections like: HDMI to LED TV and to external USB HDD. In the perfect world there would also be a connection for power supply.
I could only found the HDMI out + power supply but without USB support. --> The cable is officially called "Samsung HDTV Adapter Cable (EPL 3PHP) "
And then I also found only Samsung connector to USB but without HDMI & power supply. --> The cable is officially called "OTG USB Host Cable Adapter for Samsung Galaxy"
Has somebody found an adapter that suits all my needs?
Ok, if there is no other option, then I have one more question.
Will this combination work?
EPL-3PHP + EPL 1PLR --> can I combine the two cable adapters ( For playing cartoons, movies from external HDD to my LED TV via HDMI )
If this combination works then I will only miss the power supply.
I wanted to posted some url's to Amazon so you could see which cables/donlges/adaters I am reffering to but I cannot because I have not yet reached 10 posts on XDA :silly:
I hope I articulated myself and that you guys will understand what I would like to have.
Thanks in advance, Jus

[Q] P6800 7.7 NO USB audio PLEASE HELP !!!

Hi.I'm new in Android world.
I work on my car stereo project and it's in the middle and I stock with usb-audio out issue.
I have a Samsung tab 10.1 from local AT&T store and P6800 7.7(int.ver.) that I just bought to use as a head-unit in car.
When I connect 10.1 tab to DAC the power lights comes on, on DAC and HUB and it gives me audio out of USB (30pin) .
When I connect P6800 to DAC the power lights comes on, on DAC and HUB but i'm getting message warning "high power USB device connected... cannot access this device." and sound goes to internal speaker.but USB-HUB powered by external power supply.
Restarting with connected or disconnected HUB makes no difference,same result no sound via USB.
The 10.1 already came with ICS4.0.3 and 7.7 I updated via Kies to ICS4.0.4 and both support USB-Host.
I'm using 30pin -->USB-HUB OTG kit --> Behringer U-CONTROL UCA202 DAC.
Question is WTF is wrong?
Should I flash 7.7 to ICS4.1 or any other custom ROM?
Anyone ???
Thanks

Can u charge 10.1 with pc? In settings, go to dock option and check it, you must use the original dock, 3rd party accessories are no guarantee to work. Try flash custom roms but i doubt they will also cause ppl hardly succede with hdmi let alone dock sound, plus atm they still have problem with stable roms :|

Thanks for reply.
Yes it can charge from PC, even if it's says "Discharging" it's actually charging but slow.
Also I just tried to connect already powered HUB to 7.7 and it's doesn't give me warning about " Hi-power usb connected but can't access " anymore,
it looks like exact like it would 10.1 connected with green lights on DAC and HUB but sound plays internally no mater if dock opt. checked or unchecked .
I assume 4.0.3 vs 4.0.4 does not related to that issue as well as 3rd party accessories since it's works with 10.1.
Flashing custom ROM and loose some features is doesn't sounds right too.

Well they are 2 different devices, you cant say that. The softwares are different. I noticed you use the word hub. Try connect directly to the tab, and try different accessories. Its hard to compare different devices even though they share similarities. Perhaps compare 2 7.7 is better.
Or youcan send me the tab and i can have a look at it. Mine works perfectly
Sent from my GT-P6800 using xda app-developers app

What accessories do you use to connect your 7.7 to DAC?
I mean HUB or otg cable?
By the way usb flash drives and memory cards works fine with 7.7 via that usb HUB. I'll buy otg cable to see if it get me audio out.
Here is the HUB

Nope this rubbish won't work. Haizz. Wasted time with you when you insist on your mistakes. Hubs won't work ever. From 2.0 speed you get down to 1.1
Sent from my GT-P6800 using xda app-developers app

OK I got this OEM Samsung USB Connection Kit direct to DAC. DAC light is on,"USB connector connected" came up but same result.Only internal plays.

OK I GOT AUDIO OUT with "rubbish" usb-hub mentioning above but only when I use "USB AUDIO RECORDER PRO" app. So it's not hardware issue it's on software level.
How to make it happen with other apps without flashing? I need to make it work with any internet radio apps.

Ok it was purely luck. Otg are purely for connecting external devices to your tabs. It is not meant for connect your tabs to other devices. When you connect it to the PC you can see that it require driver for Samsung for the PC to recognize it. This tag does not have mass storage mode, it only has mtp and ptp mode. So the proper way for it to function as media storage is to connect it to the PC, or having a media player can function as the PC would, but I doubt there is such available. Maybe you cab try Ubuntu embedded? Again I don't recommend such measure. It is getting too complicated.
Or you can also build a media player with driver speicifically working with this tabs to specifically pick out the audio output from the USB
Or you can use the original dock and connect the audio route. It is much simpler
Or you can switch to apple devices, they are popular and get supported well.
And you can send the tab to me
Sorry buddy, you ran out of luck
Sent from my GT-P6800 using xda app-developers app

"build a media player with driver" OR "use the original dock" are not the options, and apple is not even under consideration.
Actually I do use original dock ,but it does not provide the options to get data of USB, it's for charging purposes only.
So I just removed that 30-pin connector and used one from USB-hub.
The only question is to find player that capable to send sound to USB.
ANYONE PLEASE?

God with this Guy. With the dock not only you get sound output but also HDMI. go snd buy the original one
Sent from my GT-P6800 using xda app-developers app

The original vehicle mounting dock has sliding 30pin to round connector adapter only and cable with usb to that connector is included.
so what hdmi you talking about? Unless you talking about different dock but I'm talking about this to be able to use it in car

No the stand dock on table, the car holder are just for holding and charging, if you want you can stick the desktop dock on car surface, or connect the car dock to the stand dock
Sent from my GT-P6800 using xda app-developers app

Yes I can but it does not give me USB-audio out anyway.
It's a driver issue.I can flash to custom ROM but still did not confirmed what ROM support USB-audio.

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
