Dunno, I've seen the device has a dummy Alsa device. I don't know if the device has the capability to play sounds, maybe if it gets recognized by the kernel drivers (or a custom kernel?) it *could* be able to be used. No idea xD.

Guys,
Sorry, I’m a little late.
I’m sure all “battery charging logic” has to be on the chip, not in software.
Not sure about why LED didn’t turn green on rooted nook until you went to stock firmware.
Might be all you have to do is reboot?
And about battery drain with host mode enabled.
I have a feeling (but no proof), it has to do with schematic.
Something was not thought over, not tested or omitted to reduce price...

BTW: What component supposes to prevent deep discharge even on stock firmware?
And what doesn’t let battery charge properly after deep discharge?
I guess it is faulty “charging logic” (which has to be on the chip)
What else could it be?

Roger,
Are you on stock still?

Automount? No.

Code:
mount -o rw,remount rootfs /
mkdir /thumb
mount -t vfat /dev/block/uba1 /thumb
I can easily get a thumb drive to work on a hub, I've not gotten mine to work plugged directly into the Nook.

good job! usb mouse?
Host mode works like charm! it is simply amazing!!!

I wonder if it is possible to somehow get mouse cursor working, possibly imbedding it into no-refresh enabler since it does dithering with screen anyway and mapping DPAD to changing cursor possition! that would be really * * mighty and magical * *

anyway have you tryed this linux installer on Market?

All modern batteries come with a chip that

- prevents the battery from overdischarging
- monitor the battery temperature
- handles different charging modes (constant current charging, constant voltage charging)

A bit more of info from the EEVBlog

I picked up a USB audio adapter. It happens to have volume buttons on it.
It is recognized as an HID input device. Pressing the buttons causes speaker icons on the Nook.
However, it is not recognized as an audio device.

Code:
#cat /proc/asound/version
Advanced Linux Sound Architecture Driver Version 1.0.18a.

#cat /proc/asound/cards
 0 [Dummy          ]: Dummy - Dummy
                      Dummy 1

Wow! Are you building a media center from your nook?
Sorry, cannot tell anything useful…
Yet I was wondering if there is an easy way to find out if a device (VEN_####&DEV_####) is supported on an android (OS version)?
Or if it’s supported on Linux (i.e. has drivers/sources), it’ll work on an android too?

sounds great! do you think that drivers will be needed. they maybe can downloaded somewhere. Since linux Ubuntu runs on nook and Puppy linux, which will be more usefull is comming up, it might be enought to down some driver for linux. btw check out update in a thread http://forum.xda-developers.com/show....php?t=1583141

There are reports of this exact device being used on Linux.
It's just a question of getting the drivers all in there.
I was waiting to hear from mali100...

I am trying to put together a media center, but also a portable recording solution.

C-Media USB Audio Device
0D8C:0008

Note: If somebody really wanted a tiny two button remote, they could use this
and map the VolUp/VolDown (for just this device Id) to PageUp/PageDown.
