:<Question> 3.1: USB connection feature requirements </Question>:

Just wondering. You still need an OTG cable to connect camera/drive/other, right?

Yes, you can't get around physical wiring differences.

USB cable for xoom
Surely you can use the USB cable that came with the xoom and attach a female to female adpator and run your camera cable from that. You dont really need to buy a specific OTG cable. Well I think that would work.

Nope is doesn't you need a otg cable. I tried it myself a few months ago, ended up buying 3 cables to get that worked.

The wire that comes with your Xoom is wired differently than an OTG cable. The Xoom wire is a client wire. The OTG is a host.

But with 3.1 + an OTG cable, can you use the USB Host function without this hack :http://www.slatedroid.com/topic/15979-hack-enable-usb-host-mode-ie-thumb-drives-on-the-xoom/ ?
You just plug your OTG cable and it works ?

It seems there is still no way for a stock user to use a USB stick via the OTG cable because there is no app that recognizes it that way, Android still requires root to access the file system or both.

[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.

[GUIDE] $7 cable that triggers Car Dock Mode (NO SOLDERING REQUIRED!)

WARNING! CONNECTING ANY CABLE TO YOUR PHONE THAT DID NOT COME WITH YOUR PHONE IN THE BOX COULD DAMAGE YOUR PHONE, YOUR COMPUTER, THE ELECTRICAL WIRING IN YOUR HOUSE, AND IT COULD KILL YOU!
you have been warned
Soooo I recently stumbled across this thread http://forum.xda-developers.com/showthread.php?t=744636&page=3
that states that if you short pins 4 & 5 on a micro USB connector and plug it into an HTC Desire, the phone will automatically go into car dock mode. as luck would have it, I happen to know that this is the same method that is used to trigger USB OTG on devices that support it. The wheels in my brain began to turn... $7 and a few days later I came up with this:
MICRO USB HOST ADAPTER + A BIZARRE A TO A USB CABLE = A CHARGING/DATA CABLE THAT TRIGGERS CAR DOCK MODE!
I have tested this on my G2 using Virtuous G-Lite 2.0.1 and it works perfectly, but YMMV.
I got the USB host adapter here
http://www.amazon.com/Micro-B-Adapt...3?s=electronics&ie=UTF8&qid=1328093895&sr=1-3
and the A to A USB cable here
http://www.amazon.com/StarTech-com-...3?s=electronics&ie=UTF8&qid=1328094123&sr=1-3
Just in case you haven't already figured it out you just connect the female end of the OTG adapter to either one of the male ends on the A to A cable, then use the cable as you would any other charging/data cable in your car. the only difference is that now your device will automatically switch into car dock mode when you plug it in! you could also connect this cable to a dock that has a female micro USB connector on the back (like the G2 OEM desktop dock here http://forum.xda-developers.com/showthread.php?t=1473718) and create your own car dock!
an extra word of warning, DO NOT USE THE A TO A CABLE ON ITS OWN FOR ANYTHING! this is a non-standard conforming cable that would damage any two USB devices that you attempted to connect with it. I have no idea what it's intended use is on it's own, but don't think that it is the same thing as a USB data transfer cable (transfer cables have a chip inside the cable that makes the two connected USB host devices see each other as USB slave devices. this A to A cable is just a copper wire)

Nice, I didn't know people wanted this. I got a premade cable. Off ebay that triggered car mode no mods needed and it was a buck. Lol

My guess would be that the cable was not intended to trigger car dock mode, it was just poorly made. a really bad soldering job on the pins would short pins 4 & 5 and do the same thing. Other people have reported this same behavior when they buy low end cables or get water in their micro usb ports.

I tried this and it seams to work but all it does its launch tunein radio, any idea how to change it to other apps such as torque? Thanks

The short thing does work. I my self stumbled on to it while repearing a aftermarked charger .. I opened up the mini usb side and it had a resistor on jumping pin 5( - ) to pin 4 . With the resistor on it charches with the resistor bypassed and just jumped to pin 4 it goes in to car dock mode. Also my friend got a samsung infuse and came with a hdmi dongle usb, so out of curiosity hooked it up to my g2 and it whent to car dock mode

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.

Actually, I used it on stock 2.3.6. As far as I know, that's more or less all that the the laptop docks are (with some added signal to know to use webtop when connected).

Cable Matters USB-C To 4K HDMI Adapter With Power Delivery (2017 MacBook and IMac, Galaxy S8 and Thunderbolt 3 Compatible) In Black

Why not use a chrome cast?

use this usb c hub its the best by far, the only adapter to do 4k 60hz for gaming needs etc but only bad thing is its got usb 2.0 port instead of usb 3.0 which is a bottleneck for hi speed file transfer needs. but other than that it does everything you need it to do like act as a ultra low power 4k 60hz tv box, ultra low power 4k 60 hz gaming rig(emulators etc) and offcourse charging all at the same time via quick charge 3.0 thats 30 watts max. my setup consists of 2x usb gamepad, 4k 60hz hdmi tv with HDR, a 500GB external 2.5"inch hard drive. a usb keyboard and a wireless 2.4ghz mouse all with this adapter oh and another secondary usb 2.0 hub with power and sd card etc connected to the first hub.

you may have initial problems setting up all your devices and enabling enough power to power the phone and the devices so always use powered usb hubs so you dont create a situation where the battery drain is larger than the power being provided. i had to fiddle around to find the sweet spot. for example i realised there are different scenarios when connecting the devices to usb type c hubs. some for example this one im using from scan needs the power charger to be connected the last after connecting hmdi and usb if not done last the power provided is much less or the drain is much higher. when you connect the power leade to the adapter the hdmi display gets cut out and you have to then reconnect the hdmi display to re enable it. i have tested a few of these usb type c hubs with hdmi etc they all seems to have this problem they wont all (display, charge, usb) work when connected at the same time for example connect the devices and display and charge to the hub then connect the hub to the phone, you have to re insert it into the hub after disconnecting it to enable it.
after fiddling around with different combinations for a few days now i have finally been successfull with having a usb external hard drive, hdmi 4k 60hz display and a keyboard and mouse and phone having enough charge to stay on green led while i do everything such as web browse, play games, watch 4k and use keyboard and mouse on my htc u11.
ive noticed when i was using a standard cheap usb optical mouse those with flashing lit leds on all the time caused my charging power to drop so after changing the mouse for a optical 2.4ghz usb mouse it seems to have increased the power for charging which nipped it in the bud for me and my setup. now my htc u11's charge led stays green all the time.
further from my experiments i realised some methods of connecting caused quick charge 3.0 to work but as soon as it reached 100% charge the charge power would drop so slow battery drain would start to happen while other scenarios reduced this battery charge drop rate and was slower in draining. heres another scenario when i plugged everything the display the charger and the usb external hard drive to the scan club 3d dock the hard drive wouldnt work at first then i realised my external hdd was formatted ntfs since it allows large file sizes for 4k movies. then i had to format the external hdd as exfat since ntfs is not recognised in android only fat 32 and exfat. fat 32 dosent allow file sizes above 4gb while exfat and nts do so exfat was the best option for formatting my external hdd since it was recognised by wndows and android. second problem factor i had was that not all secondary hubs would work. i first tried a usb 3.0 4 x port hub (not extrenally powered) and a cheap 4 x port usb 2.0 hub but they wouldnt work with my external usb 3.0 hdd the drive would appear in file explorer but wouldnt show its contents. so then i finally got a usb 2.0 hub with sd card and external power and 3 x usb 2.0 ports and that worked!!! so when connecting a secondary usb hub its most likely needs to be externally powered.
with the new usb type c 3.1 port comes lots of bugs that need to be hammered out on the software firmware level before its all totally plug and play. my htc and the scan club 3d hub didnt work too well at first but after a few htc u11 firmware updates things were alot smoother.

Hi there,
I ordered this one for Amazon "USB C Hub, Excelvan 5 in 1 USB Type C Hub HDMI 4K Transfer with 3 USB 3.0 Ports Power Delivery for new MacBook / MacBook Pro 2015/2016, Smartphoe, Tablet and other USB C Port Equipped Devices" (can't post link as I'm a new user)
I plug in but get nothing it lists support for the HTC 10 which I thought used the same standard.
My phone is on Oreo, can anyone verify HDMI out works for Oreo still?
Is there anything required to make it work other than plugging in? The USB ports work so thats a start. Also I wonder, the devices I'm plugging in only support 1080p so do I need to change the phone resolution first or should the phone do that automatically?
Thanks in advance!

I purchased another cable and it works! So Oreo isn't an issue.
For those interested the cable purchased was from Ebay UK, search for "Type C USB To HDMI HDTV Cable External Display Adapter for HTC U Ultra U11 10"
