[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.

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.

High powered usb problem

Ok...so I have ordered 3 different adapters for my samsung galaxy note 10.1, ive tried it when it was rooted and on stock, nothing works, basically i get the usb adapter, plug it in, and the ps3 controller works for like 2 hours...then doesn't work on any of the adapters, it stops reading the ps3 controller and says its a high power device and that's it, , it think it stopped after the controller conected to the ps3 again? can someone please tell me what to do? ! im just fed up!

I use a USB OTG cable and find it only works with devices that don't require power from the USB to work. Maybe a ps3 controller needs an external power supply.

maybe, but it's so frustrating because i saw youtube tutorials and tutorials on here about what to do even with xbox controllers, im just having no luck with it at all, doesn't even allow me to do it wirelessly, but usb memory sticks work fine just the controllers...

I'm not sure if this would work but since you have got 3 cables experimenting with one wouldn't be a great loss...
Usb cables have 4 connections. 2 are data 1 is +5v and one ground -
If you cut about half way into one of your USB OTG cables and found the +5v and ground - cables and cut them so your tablet can't see a load then with another USB cable (male plug side only) connected the +5v and Ground - only to the female side of your USB OTG only so it could power the ps3 controller.
Then you would plug the extra USB plug into another USB socket like a PC or laptop or similar to power the ps3 controller.
Just an idea.
Edit: Or just find the red cable in one of your USB OTG cables and cut it. You will have to charge the usb controller another way though.

Your PS3 controller is attempting to charge its battery from the USB port/OTG connector. The port can only supply amperage for so long before protection circuitry kicks in and keeps itself from melting down. Atleast that's the way I would do it if I were an electrical engineer

Yes even data cards do not work

I find I can use memory sticks OK but anything that draws a lot of current gets the (in)famous "high power USB device" notification...
It's a pain in the bum as I would like my $600 Note to use the 1Tb NTFS drive my $400 A501 uses with no problem whatsoever...

Today there are whole host of usb powered devices some are good and some are cheap may be the concept Samsung had was to make sure some device does not pull power more then the tablet can provide and in turn does not overcook some of the components so that have built in a failsafe may be because the single port does multiple functions this has been provisioned

Yeah but when I used a powered HDD it fried not only my Note10.1 but also the portable HDD too... Not happy...
I think it killed the battery to be honest as it got REALLY hot and the battery dropped from almost fully charged to depleted in about 15 minutes... Also killed the digitiser but the pen still worked. Turned off and left overnight and tab was completely dead next morning....
Very expensive paper weight...:crying:
So I had to go out and get another one, this time 32gb 3g instead of 16gb (eating rice and tuna for the next month or 2)...
Won't be connecting another drive any time soon...

thanks

external hds and otg...

looking to go completely wireless with a hard drive for the note pro for movies, music, ebooks, etc. i bought a toshiba 500gb porta-harddrive (UNpowered) and a usb2 otg cable... but its not quite working because the drive doesn't pull enough power to run (it just sits there ticking). when i plug the drive into a powered usb hub and the hub into the otg, it works fine; but then i'm still tethered by the hub power cord.
anyone have a completely wireless setup that works and care to share what equipment they're using? i'm thinking a usb3 otg cable might do the trick, but haven't been able to find one locally, and want to be certain before dealing with the shipping hassle.
thanks,

The additional conductors added in the wider micro USB 3.0 cable are for data, not power. What you could do is get a USB battery...

I have a Seagate GoFlex 1Tb hdd. I formated it exfat and it works fine with a mocro-USB 2.0 otg cable or with a new micro-USB 3.0 org cable. The NotePro has no problem powering it with either cable.

thanks for the response. two things:
1) can you look at the fcc sticker on the hard drive and tell me what the power draw is? it should say something like 5V+- XXX mA. i'm curious about how many amps it pulls. i think the problem with mine is that it lists 1000mA, which exceeds both usb2 (500mA) and usb3 (900mA) specs.
2) is your tablet rooted? not sure it matters, but i'm reading mixed opinions on the matter in the fora, and it might be a factor.
i've also formatted exfat and that didn't seem to fix it, and it works fine attached to a powered hub, so it looks like its a power issue.

yes, but usb3 allows for more power to be drawn then usb2 according to the specs. turns out not enough for the hard drive either way unfortunately so the battery might be the way to go. would need a 'y' cable though since there is no power input for the hard drive.
now i'm thinking of just getting one of those hard drive/battery/wi-fi hotspot combos that seagate or corsair makes.
thanks

1. Power draw is not listed on my HDD. The part number is 9ZF2N5-501 1 TB if that helps. The only connector is theUSB 3 connector, no seperate power input.
2. No, my NotePro is not Rooted.

My two setups
Seagate wireless plus 1Tb
As long as the battery of the hdd has enough power to maintain its wifi service this is the absolutely no wires solution. Easy to operate but slow in terms of data transfer. Fast enough to watch Hd-video though.
Hebron connector
EasyACC powerpack 10000mA
Toshiba STOR.E basic 500gb ext. USB hdd
In this setup there are cables.
Powerpack to connectorä
Hdd to connector
Connector to Note
Advantage of this setup is that I can read sd Card, connect USB stick, mouse,
And it's still just a little more than a handful of equipment. The Weight is not worth talking about

thats exactly what i was planning on using it for. i've never been able to stream anything via wifi to the tablet (netflix is okay, i mean from my local drives), though, as it always buffers and stutters making video playback unwatchable. probably just my home network, but for almost 200$, i'm a little gunshy about this option.

will try this. cables connecting the devices i don't mind... i just don't want to be tied to a wall outlet. especially if there are no walls available. :cyclops: i went with the 16000 easyacc for $50, and the 9pin usb otg y cable for $9; so that setup is much cheaper then the wifi/harddrive/battery device.

final outcome
thanks to everyone who responded with suggestions.
so i ended up getting a power pack, and an otg y-cable to hook up to the hard drive. i actually bought two otg cables, one usb3 9pin and a usb2 5pin. the usb2 had a micro female connector for the power, while the usb3 had a standard male connector.
the usb3 otg didn't work. plugged the power pack in, plugged the harddrive in, plugged it into the tablet.... nothing.
the usb2 otg did work, luckily the power pack had a male-female adapter. tablet recognized the hard drive was present, but said it was blank, and es file explorer popped up a warning that otg only supported fat32 (hard drive was originally exfat). so after reformatting to fat32, everything seems to work well enough.
i don't know why the usb3 cable doesn't work, it may just be a dud but i have nothing else to test it with. all in all, an annoying and frustrating experience getting this to work. i don't see why anyone actually thinks these sorts of tablets are going to become laptop replacements when basic functionality requires so much teeth pulling.
so it goes,

MHL + Power Adapter not Charging Device

So I recently got a MHL/OTG adapter off of ebay. The HDMI out and usb ports seem to work no problem. My problem is that when connecting my charging cable to the MHL hub my device isn't getting any power. I have no indications of my battery % going up. That means if I were to stream a movie onto my TV it would work fine but I would run out of battery fast. Does this seem like there's something wrong with the MHL adapter? Is my samsung battery charger not strong enough? Any help with this is greatly appreciated. I have done a bit of research on this and found mixed answers.

Actually... That's normal... An otg adapter puts your device into "power output" mode so it can power a flashdrive or other storage device... So the input/charging mode gets turned off.
Plugging your charger into the hub helps power the external devices so they don't kill your battery so quickly...

No. MHL 3 is meant to charge in parallel. Works on mine. It charges at 700mA only though, pretty slow. You can check the current by Synapse App + Skyhigh Kernel. I think you can configure higher charging rates as well(didn't try). MHL 3 is speced for 2A current.

Yeah... MHL works that way... But the OP says it's also an "OTG hub off ebay" .... So were not just talking about a straight MHL adapter... If it's an OTG hub triggering OTG mode on the tablet... Then it won't charge and it's not suppposed to.

Hi, I also have a MHL/OTG adapter like yours (MHL/OTG/Card Reader) MHL-HDMI works flawless but OTG doesn't.
A USB pendrive that works flawless with an OTG cable it doesn't recognized in the hub while MHL>HDMI it's working.
@xmilar can you please post the link to the MHL/OTG adapter you bought and while yours not charge, are MHL+OTG working simultaniusly?
Thanks!

I've looked into MHL adapters for my Tab S 10.5 and LG G3 but it would require multiple cables and if I replace either or both items and the new item uses a different MHL, I would have to spend more money. I ended up just buying a Chromecast that does the same thing and wirelessly. Best $30 I spent

Hello, I ve bought an MHL adapter, the one with usb connector to charge the tablet when using the mhl, anyway nothing is working. The tablet doesnt charge, and shows 2 times the following : HDMI Connected, then after one second HDMI disconnected, two times. On my Sony phone works with no problems. I have skyhigh kernel and stock rom.

Probably it's not MHL 3?

Sorry for the late reply, if is not MHL 3 why is it working on my Sony Z1 compact with 4.4.4 rooted also.

If the adapter works on a Sony device then its probably based on a standard micro USB connector. According to the wikipedia entry for MHL newer samsung devices use a propriety 11 pin micro USB connector for MHL. There is mention of a "tip" to adapt between 11 pin and 5 pin, perhaps you could buy one of these?

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?

USB OTG and Y cables?
Sent from my SHIELD Tablet K1 using Tapatalk

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
