Root Usb otg

[OverByter]

Does anyone know of any rom that supports usb otg host mode?

I thought 3.0.x and up supported it. Do you have a "on the go" usb wire that you have tried, with the phone? Same goes for hid support too. I thought, anything honeycomb and up supports that as well. Not unless, it has to be turned on like some other devices.

This video is in another language, but they have it running on a 3D, so I would assume the same goes for our phone.

Here is a "how to" on making a otg usb cable.

It works on CM9 0.7.4 with Anthrax kernel

 

[jvillejoe]

Yeah, looked it up on my hd2, and its kernel related.

All research I have done points to only hardware V1 having support for it. You still need a kernel with support (Anthrax does I think), and a rom that supports it (no current ones that I know of). Worse, all of our phones are Hardware V2.

I have an OTG cable, but I have yet to get it to work (I haven't put a lot of effort in yet).

I think I saw some posts on anthrax forums that someone got it working on hardware v2.

I'm on hw0002 and it is working. Needs to have a powered usb hub or in my case I made a y cable and powered it with the phone charger

What kernel are you using? and rom? Mind snapping a shot of the cable you made? I would like to connect to my tv but sense the micro usb doubles as the hdmi I am not sure how to go about this.

I'm VERY interested in your setup, please post it.

It would (possibly) mean carrying a bit less to work if that functioned.

 

[OverByter]

Yes, please post your setup. I am really interested in using my usb dac/amp with my phone.

Using CM9 DT0.7.4 Anthrax kernal 3.2
In /system/ect/vold.fstab you will need to add

dev_mount usb /mnt/sdcard/usb auto /devices/platform/msm_hsusb_host.0/usb1

and add usb folder to /mnt/sdcard


For the power side of the cable do not connect the shielding green and white wires it interferes with usb connection technically you only need the red and black wires for the power supply.

Still no luck on mine.
I will have to mess with some cables tomorrow and see.

You need to splice in a power cable, as in jdt's pic. The phone won't power the USB device.

Couldn't you just use a powered usb hub instead?

Did that with two cables, CM9 and the added line, no luck.

Still something missing.
