BlueTooth not working on my HP Probook 4720s
- by mtrento
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 :
