Comment 52 for bug 762964

I have the same issue with Bluetooth.

Notebook: DELL Vostro 1015 w/ Atheros Wifi+BT combo.

lsusb:
Bus 004 Device 002: ID 0cf3:3002 Atheros Communications, Inc.

uname -a:
2.6.38-8-generic #42-Ubuntu SMP Mon Apr 11 03:31:50 UTC 2011 i686 i686 i386 GNU/Linux

hciconfig:

 DOWN
 RX bytes:0 acl:0 sco:0 events:0 errors:0

sudo hciconfig hci0 up:
Can't init device hci0: Connection timed out (110)

"sudo service bluetooth restart" does NOT work for me.
