I've read the thread about enabling USB Host through a hardware mod of a powered USB hub, but I am hoping the Atrix is able to accomplish USB host mode via software hack? From what I understand, it is an ICS feature but requires kernel level support, so am I stuck without it before Motorola releases official ICS for Atrix? It hasn't worked with CM9 or 2.3.6 Blur ROMs.
Separately, I am looking for any webtop installs that have worked with this...stock webtop didn't enable digital audio out via USB.
FYI, I am looking forward to this to use my USB-powered Digital-to-Analog Converter and headphone amplifier (Fiio e7) with my Audio Technica ATH-M50 studio monitors. The audio signal out of the analog jack is not quite sufficient.
Any help my Atrix brethren?
Any help?

The atrix supports USB host even with the stock kernel. There are 2 things you should consider though.
1. The ARM devices need a charge on the USB line to go into host mode, so a software solution is highly improbable
2. You need a kernel or kernel modules for your USB audio stick to work properly in addition to some also, or any other mixer that supports picking the output.
Wow, so not even with an OTG cable? It doesn't even need to install drivers, was hoping this would be workable. Thanks for your insight.

The drivers are there, but you need the signal on the usb which you can get through an otg +powered usb hub. It works fine than. You can use the hd dock instead of this though, its way less messy that way.
Thank you for your explanation, looks like I will need to wait to see what motorola puts out with the ics update.

Hi,
Are there any GB ROMS or kernels that support USB Accessory Mode? The main reason I put custom firmware on my phone was so that I could develop hardware to interface with the phone. thanks!
I also want to know weather it is possible....
I do not believe that the Vibrant hardware supports USB Host mode. To do that the vibrant (and it's battery) would need to provide at least 100mv (I think thats min) to the 5v vbus to power the accessory.
The USB port is now set to draw power (for charging etc) not provide power.
edit: check out the Nook Color forum. There they have (sort of) gotten the Nook to support USB Host mode using a powered USB hub. It took a kernel change and app to switch. It's different on the Nook as it uses open source bootlaoders (Das u-boot.bin) vs. the closed source Samsung boot.bin, sbl.bin we are stuck with.
I looked into this a while ago. The best efforts were attempting to use Sven's Nexus USB Host Mode hack. Unfortunately the hardware is so different between the two models that the hack simply wouldn't work. No one else it seemed took up the torch to make this work. Can't seem to find the thread discussing this. It was like 8 months ago.
And the power issues of the phone are easily negated by using a powered USB hub in the chain between phone and device. The only limiting factor for the Galaxy is not having a supported driver.

Officially accessory mode is implemented starting with Android 2.3.4. In this mode Android phone is an accessory to some host external hardware and receiving power (0.5A) out of the host.
Host mode is implemented officially only on tablet Honeycomb 3.1. I think Google made external usb devices such as memory, keyboards, and mice usable for Honeycomb tablets.
If you are interested find IOIO project which uses ADB for bridging external hardware on Android before 2.3.4.
Any update on accessory mode in gingerbread? I see that some new 2.3.5 stuff is out.
Would like to get working on developing external hardware to interface these sweet machines.
Just found this link: http://www.techspot.com/news/45032-rumor-ice-cream-sandwich-coming-in-october.html . Even if the Galaxy models get usb accessory mode, it looks like there is a new line from samsung that will not only support usb accessory mode, but will support usb host!
It is my understanding that android natively supports usb. My question is, if I get a micro usb to usb adapter, and then plug in a usb keyboard, I would be able to use the keyboard to type documents. Any thoughts?
(I have a rooted nook, but I got the update before I could block them, will revert back soon)
currently no. The android or in this case nook skinned android kernel has to support usb host and usb keyboard inputs which it doesn't. But it probably will in the future when the devs release android 4.0, because ICS needs a different kernel then the current nook tablet kernel. But anyway what keyboard do you have, because you can only connect bluetooth keyboards and also only if the developers can enable bluetooth on the nook.
It also depends on the hardware support. I don't know if the TI chip has a host-only port, or if it supports OTG (On-The-Go) dual mode operation. It probably does, but I've not seen anybody verify that.
it doesn't support USB keyboards. I have a female USB to micro USB for my galaxy S2. I tried to get a USB sick and 2.4GHz mouse and keyboard on the nook but nothing worked, and yes it both works on my galaxy with the stock ROM

The NT can support usb gadgets and usb hubs but it need to be enabled in the rom and the must have the module, the NC has this feature and i hope our great devs can implement this on the NT.

im looking to use a usb 3g modem myself with my tablet ,
ive read a bit on the latest engadget article about the other older e paper nook that was done with a usb keyboard i even went as far as to contact the guy who did it and he told me what to look for , hardware wise to see if the NT could do it ,
yet without kernel support or the module being compiled into the kernel we have already on the tablet , theres not much hope , but i believe it can and will be done , if not im gonna have to get an ipad with a 3g data card in it cause i have to have data access wifi hotspots just not cutting it..
Hello everybody,
I know that the scene is working really hard making and porting ROMS for the NT, now that CM7 (ALPHA) is out... I'm curious if is a CHANCE or light in the future to use a micro USB/HDMI output to be able to connect the tablet to a HD TV using MHL.
PS: Is the CM7 KERNEL capable of mounting or recognize keyboards, gamepads etc etc with micro USB port.

I'm pretty sure that video output would require some hardware support, soas far as I know that won't be possible.
I don't know about using the USB for external devices, but if they ever figure out the "magic number" it should be possible via Bluetooth.

MHL is pretty cool .But AFAIK Nook does not have a HDMI out function. B&N would've advertised the **** out of this feature , coz it would have been a great advertising feature .IIRC most 7" tabs lack video output .
USB OTG has not been described as a feature and seems very unlikely .
If the bluetooth module (present but disabled) is unlocked and drivers installed , then BT keyboards, gamepads possible in the distant future .
Hav fun

It is possible to pipe the display signal with software plugin and rebuild in PC via normal USB connector. It works in PSP.
Can someone send me the internal zip for cm7 please

Hi Folks,
I have the OTG cable and USB Y cable working my touchpad with 7/30 CM9 nightly... I would like to purchase a USB wired ethernet adapter. Has anyone tried and know of one that would actually work on the touchpad with CM9?
Thanks a ton!!
Anything that Android 4.0 supports should work unless its limited by our kernel. I'd say there is a good chance this one would work as it mentions plug and play compatibility on Android 3.2+. But there could be kernel limitations so you may want to get another opinion.

Right now, I'm using an HTC EVO 4G LTE, running ICS. Now the source code is out, however, no one has yet to add USB host capabilities to their kernel, so I figure I might as well do it myself. I read on kernel development, and I have a surface level understanding, but I'm just interested in adding the USB host capabilities. So how would I go about doing that? Thanks.
IIRC ICS should have OTG that works for keyboard and mouse. Of course the microUSB port on your phone needs to have the hardware to support OTG and also may or may not supply power.
Yeah, the hardware on the EVO supports it, it's just that HTC never enables it in their kernel.
