I confirmed this works on the current git kernel with

echo 1 >
/sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/neo1973-pm-bt.0/power_on
echo 0 >
/sys/devices/platform/s3c2440-i2c/i2c-adapter/i2c-0/0-0073/neo1973-pm-bt.0/reset

[CARE!! do not do echo 1>blah ... make sure there is a space after the 1
.... this does something quite different, thanks to Werner for spotting]


You can do

mount -tusbfs usbfs /proc/bus/usb

and then you can find the bluetooth device in

 $ cat /proc/bus/usb/devices

I can confirm both working... don't forget one of them is mounted at 45
degree angle, and that the result is signed, so you can see something
like FFFFFFDC which is -36mG.

I added alsa driver support to the git tree, I find the device is
recognized by Alsa okay

$ cat /proc/asound/cards
 0 [neo1973gta02   ]: WM8753 - neo1973-gta02
                      neo1973-gta02 (WM8753)

I don't have the /dev/snd/* in this rootfs or /etc/alsa/alsa.conf etc,
but I will add it and test if you still fail on the latest git.

Now I can resync to mokopatches Willie's patch is already there.

So please retry with current git.
