the blue tooth on my ubuntu 11.10 does not work. When i try to ad a device it scans indefinitely and never find anything.

Wireless is working perfeclty and with windows 7 it is detected.

As i read somewhere , the bluetooth is not listed in the usb devices.

Is it supported under ubuntu?

here are the output of the various debug command i tested :

hciconfig -a
