[Q] HP Touchpad OTG support? - TouchPad Accessories

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.

Sabrent 7-PORT USB 2.0 HUB WITH AC POWER ADAPTER. Will it work with OTG in ICS?

Hello,
I think I found a cheaper alternative to Lapdock, but IDK if and how this can work or not.
I found something with external power here and I'm wondering if we can attach a mouse/keyboard with it.
Thanks in advanced,

It should work as long as you have an OTG adapter or cable that shorts pins 4 (the ID pin) and 5 (ground) that would then connect to the powered hub. These can be bought pretty cheap or just make one with a spare cable. The phone needs to know it is in USB host mode (shorted ID to ground) and there needs to be external power for the peripheral devices.
I just recently bought this , this, and this. The hub has two usb's: one for the phone, which has the otg cable, and the other for power (which I connected with the extension cable). You can then use your regular usb wall charger. Everything works great (attach any usb device you like) and when you attach a micro HDMI to regular HDMI cable to a TV/Monitor, you got yourself a computer like setup. I haven't tried it, but I think you can even attach external storage to it as well.

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

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?

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

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
https://www.youtube.com/watch?v=x3miSU6FpDg
i bought this one , it work not enough quick and don t know if i did well,
i use mode 1 , plug hdd then plug charge, in video they use mode 2
