I've tried too many glitch kernel builds and too many ics builds to count - all to no avail. I have confirmed that my otg cable works just fine on my friends gsII. However, I still can't get anything up and running on my phone. Yes I am using a Y splitter cable. Yes it is hooked up correctly. My phone is a mesmerize (technically same specs as fascinate, just diff. provider). Please someone, I need help.
I too have been trying to get the usbhost mode to work. I have everything set up right from the guide. When i use the usb host controller app it shows its connected and ready for a usb device but it can never find one. I think were missing something or I am doing it wrong.

Did it work before you flashed angelrom?
i didnt try it before my friend....today i bought the converter from micro usb to usb......so...is there any service that maybe did not is enable in the custom rom....and cant run the usb host....
It's unlikely that it's the ROM, as this is a feature that many people use.
It may be that what you are trying to use simply doesn't work. Do you have a USB mouse you could try? Also, is the device that you are connecting powered, or does it expect power from the USB connection?
well...i connect 3 devices... a keyboard...a mouse...and a usb strage stick....
and no led...power on...of the devices
In that case, I suggest you ask on the thread where you got the ROM. Have you already searched that thread to see if anyone else has the same problem?
i did a quick search...but i didnt find anything important...well ok my friend thx....

don't bother checking with more devices or posting in the rom thread, you just bought the wrong cable for otg purposes.
a simple converter from micro usb to usb won't do, the sgs2 discovers connected devices by the resistor between pin 4 and 5 of the micro usb plug inserted, and afaik, a usb otg cable needs a 200k resistor (if you decide to weld one in yourself, double check the number against other threads, i am not sure about that). simple converters, adapters and even some "usb otg" marked cables don't have a resistor in there.
and if the correct resistor is present in the plug, the device should discover the cable when plugged in, and then you can connect any device afterwards and get another notification. (as is seen in the usb otg video in the accessories section.)
i hope you did not pay too much on that cable, or have the possibility to return it for a refund or exchange, because yours has little to no known uses.
Thanks Chef, I didn't know that. That's the "something new" that I learnt today
thx my friend..i give 4 euro for this ****...but its ok....
i m gonna buy....this one of nokia cable....its ok i thing right... ??? http://europe.nokia.com/find-produc...cables/nokia-adapter-cable-for-usb-otg-ca-157
I presume the usb port of the NT is unusable until a kernel level root is developed. If someone would confirm for the hell of it, please do! (I grabbed a couple usb to micro-usb converters - but, no luck...)
I didn't research the usability until after I tried using the usb port! I figured it would be enabled... why not allow a keyboard, etc.? Anyway, that explains why I couldn't find out the 'port type' in the official specs (micro usb).
Read some stuff on the Nook Color - and I believe the usb is available for it when rooted.

USB host mode is part of the android kernel since gingerbread but the ROM has to support it.

by unusable do you mean like not working or can't be connected to the computer
to root and debugging?
if you are... what the hell are you smoking?
please elaborate a little more as to unusable

I think he means, it can't be used to plug a keyboard in?
USB host mode is not supported in the stock B&N os.

Yeah - I guess as a USB host is the terminology I needed. I'm rooted - so, the Nook works fine as a device on my PC!
I just want to run devices from the Nook itself - particularly keyboard and game controllers (ps3).
It never occurred to me that it wouldn't function 'out of the box.' The only reason I can see to deny it is either battery drain or to guard against hack attempt. Pretty lame really!

Do you think it might be possible to replace elements using root to enable it?
Barring that, in one dev thread or another, I vaguely remember reference to a particular way of bypassing the bootloader lock, that if it worked would allow us to use custom ROMs but we'd be stuck with the B&N kernel. Does that sound familiar? What I'm really asking to anyone who might feel they know, is what are the odds the devs might crack USB host even if they can't get past the bootloader lockout?
Thanks to anyone with information.
Once this is enabled we wont just be able to use a keyboard, but also use it to browse your camera pictures, hard drives, etc

Cyanogenmod has USB host enabled. You could ask a cm dev how it is done. Dalingrin works on the Nook Color port, he may be able to tell you.

Yes. Once host mode is enabled you will have access to HID and mass storage. I have both on these on my ATRIX.

So I just saw a tweet about how on a SGS2 you can use a Samsung cord and are thus able to plug in USB devices. I had no idea you could do that, I knew with the Galaxy Nexus you could, but not the SGS2.
Is there any similar thing for the Amaze that anyone had heard of?

Are you talking about the USB micro/mini plug turning into a USB host port instead of a client port?
there have been hack up's for this since the N1 that even let you run a USB video card off of it (with a power adapter hacked into the USB line tho)... like this http://sven.killig.de/android/N1/2.2/usb_host/

Yea, that's what I'm talking about, but looking around online about the SGS2 all you need is that OTG cable and it works. This solution looks fairly intense, with changing the kernel and editing scripts... Thanks anyways, at least we know it's possible.
@faux said the USB OTG code is missing in the HTC kernel. so, either htc or someone write some code in the kernel or it won't happen.
Not sure if the Telus kernel is different but using the stock .config file, it seems OTG is enabled.
OTG support for Qualcomm on-chip USB controller (USB_MSM_OTG_72K) is what is enabled.
I'm curious if there is an adapter for the MHL port to a female USB port. I have one for my Xoom, and since ICS has USB host support, I wanted to try it out.
EDIT: Also when I restore a nandroid, how do I restore the kernel?
i can answeer your second question... use the nand droid helper that con made... its in the dev section or flash a ph98img with the boot.img in it manually or by computer

I got one of these cables on amazon for $15. But I can't get it to work. I want to run an app that will use my phone to control my DSLR, but can't get it's free version to see anything. It acts like it can work, but never does. I hope it's just not turned on in the leaked kernal, and when we get official ICS, they will turn it on, or at least when we get the kernal source, one of the devs will turn host controlling on.
I also could just be doing something wrong, as I've never tried this before.
Edit: it's called a usb OTG cable.
Can anyone confirm if the USB host feature works with the Galaxy S3.
Specifically, I'm interested in attaching a USB Keyboard to the device.
After upgrading from honeycomb to ICS on my wife's Galaxy S2 I found that the USB Host function no longer works and I can no longer connect a USB keyboard. (It used to work rather well).
After checking the XDA forums I see that I must root the phone and use another kernel which I'd rather not do given that the S2 is not my phone.
I'll be picking up the Galaxy S3 once the Blue-32gb arrives here in Taiwan so I'm also wondering if anyone can say whether or not the USB Host function works and if anyone has tried out a USB keyboard.
Any advice would be swell
Thanks
Works for me unrooted mate. Had a flash drive connected with no problems

Thanks for the reply.
After upgrading to ICS on my wife's S2 the phone continues to read USB Flash drives just fine, but it could not (cannot) read any other devices including USB Keyboards or a USB Mouse.
I want to be able to use my fold-able ASUS USB Keyboard to type documents on the G3 and from what I've seen, the screen is plenty big to be able to make my dream of 'ultra-portable' document typing a reality.
This, plus the fact that I haven't found any fold-able Blue Tooth keyboard that seems to work very well with the S2.

Check this video, as stated in another thread

I made my own usb host cable and everything I have tried is working. Wireless keyboard and mouse, memory stick, external harddrive, ps3 controller etc.
