[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

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.

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.

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

Picking the right sctive MHL cable for Note 4 ( Enyos SM-N910C 8 core )

Hi all,
I want to use my Note 4 as a PC with connected USB switch and a TV for a monitor.
What I know so far about the MHL cable:
1. It has to be active cable, with a power supply feeding from my 2A phone charger
2. Every article suggests that Note4 has 11 pin USB connector. So I can use it like a PC with such cable.
3. MHL 2.0 can transfer 1080p @ 60fps, Note 4 has MHL 2.0
What do you guys think, what cable you suggest that I should pick?
One would be the following, according to my research:
http://www.amazon.de/CSL-Adapterkab..._UL160_SR160,160_&refRID=1NB4JR4JTSNX4ANBM298
Cheers !

The Note 4 also supports MHL 3.0 which allows power to be drawn from the TV directly. I believe your TV must have a MHL port to utilize this to the fullest. Is this more power than coming from an power outlet? I don't know.

The cable you found should work. You may need a USB hub to use a keyboard and mouse simultaneously. I haven't tried a Bluetooth keyboard or mouse but you might be able to connect 2 devices at the same time?

Since you want to use your note 4 as a computer i recommend you to buy Samsung Smart Dock multimedia hub. I have it and my cracked screen S4 is connected to my TV and i use a wireless keyboard to browse and watch movies from showbox etc... better than any smart tv out there.
if you look on eBay you can get it cheaper, i think i bought mine for $50 almost 2yrs ago. it has 3 usb port for flash drive, keyboard mouse, hdd

My Samsung Galaxy Note 4 (N910H) can use MHL cable (11 pins) without external power on my old Samsung TV that doesn't support MHL natively (I have to use USB charger when I connect my old HTC Sensation on the same TV).
I also use Bluetooth Headset & Gamepad at the same time with no lag while on my Gear VR.
But I've never tried all Bluetooth Mouse, Keyboard, Headset & Gamepad...maybe I will try it tonight
Use you charger only to charge your phone when needed
NOTE:
I use 3 old MHL cable with micro USB 5 pins to 11 pins converter & all working well, without external power source.

Best solution I've found for being able to charge the phone, have USB OTG and MHL out to a TV at the same time is the Samsung Smart Media Dock:
http://www.amazon.co.uk/Samsung-Multimedia-Smart-Galaxy-Series-White/dp/B009KZ3XE6
...they're usually available for ~£20 on ebay. Keyboards/mice etc work fine with it. You have 3x USB ports, HDMI out and stereo headphone out (and I believe the audio over HDMI is capable of 5.1).
The one thing I can't get to work is an Xbox 360 controller (preferred over the PS3 controller I have because I'd rather wired than bluetooth). Works ok with my old S3, but the Note doesn't register it when connected. I don't know if that's a ROM/Kernel issue though, as the S3 ROM/Kernel I use has a module to enable XBox controllers.

Do OTG cables work?

I've got an existing OTG cable with micro USB. Does that work for things like thumb drives and mice using the adapter?
If not, would this work?
https://www.amazon.ca/gp/product/B0194WSKOM/ref=ox_sc_act_title_1?smid=A21TE5CLHZDYA7&psc=1
thanks..

It comes with a USB-C to USB-A adapter in the box. You should be able to plug your thumb drive or mouse into that.

I don't know why they would get rid of something as old as OTG support so I'm assuming that yes it will work.

yes otg works and the samsung smart switch lets you plug one phone into the other and transfer data

Just reading through the AT&T manual: it states clearly that OTG will not work through the supplied USB connector (p9). Nor can you use it to charge the Note 7 from a computer (p12).
With built-in battery too - hope the Note 7 isn't just another pretty fetish.

I can't get my Oppo HA-2 DAC to work at all. I tried using the included adapters but nothing. I went and bought a USB - USB C cable and that also didn't work. The only way I have been able to get audio is to use a standard charging cable (USB - MicroUSB) and put the USB C adapter on the MicroUSB end. However this charges the Oppo from the Note 7 and I can't disable that. Will burn through the battery in no time! Not sure what else to try at this stage

+1 I have successfully used a SanDisk 8gb flash drive with an aftermarket Rankle usb adapter. I have an AT&T Note 7.

I use the included USB-USB C adapter with a USB -USB Mini(?) and my Fiio Alpen. As you mentioned, the Note7 charges the DAC. This also happened with my Note4. You should be able to use a wireless charging pad to charge the Note7 at the same time. That's what I did when I was transferring files between phones. It's transportable but not very mobile.

My little micro usb fan does NOT work with the included usb 3 to microusb connector. So, i'm gonna assume OTG doesnt work as it used to.

OTG and recharging shield tablet at the same time possible???

Anybody knows if its possible to connect usb OTG host and charge the tablet at the same time, i found out a way to enable adoptable storage on USB drives so im planning to offload my console games(borderlands, half-life,etc) to an external hard drive cause i only play them at home when im in console mode, and if it is possible anybody knows where to get one from a reliable seller?

Okay, they one I've got is damaged. Gotta send it back.
The ones Exile suggested I've one of them. Though, they connect all to big female USB! So you'd need another USB cable (Big male USB to micro male USB for the tab).

I've been using this one, and it works pretty well for charging and using OTG at the same time. But it won't recognize USB devices unless the charger is plugged in, probably because it has a built-in hub.

Well actually they do, very2 slow, i hooked the OTG i bought to my charger, my tablet and my printer, then started doing some typing work while listening to some tracks on spotify max volume and at about 20% brightness,, after i finished and checked my battery it went up from 95 to 97, also tried the same with a usb attached, so for light loads it does charge but for gaming, even i lose charge when playing games such as vain glory while the tablet is directly charging so im sure its still gonna drain but probably not as fast as not charging at all, or another thing is not all OTG Y cables are configured the same me and @primaleph just got lucky with the ones we got and yours are probably the not compatible ones

A printer?
Anyhow, it doesn't show the lightning symbol if two devices like charger and gamepad are simultaneously connected. Whereas, using just one of the devices works.

Yeah i use an app called printershare, it allows me to use printers directly via usb connection cause i still own those old printers with no wifi connection costs 10 bucks for the license though, i tried with my old usb gamepad and it also charges and gamepad works, i think you need a more powerful charger, i use a tronsmart quickcharge 3.0 with a 2nd port with a max of 6.5V 3amp output which i use to charge it in OTG mode, 5V 2amp chargers should work but sometimes the power cuts out on The devices being connected, happened to me while on a boat trip, boring 2hr ride, me and GF wanted to listen to some music but we both own over the ear headphones not those little earphones, i charge my shield with a powerbank that provides 5V 2A output, plug it in the OTG and use a usb soundcard with with two audio jacks so we both could listen and throughout the trip there are times the soundcard would lose power which was pretty annoying,

Heres a screen recording where it is charging and i attach devices one by one to my shield tablet
