Bluetooth stopped working recently?

[Josef Wolf]

Hello,

I had bluetooth working fine for several years on two laptops here. Last time
I used it, (2011-08-03) it worked like a charm. I haven't done any changes
on those laptops except running "aptitude update && aptitude safe-upgrade".

Since then, neither hciconfig nor "hcitool dev" shows me any BT devices.

I am pretty much sure this is not a hardware problem, since the hardware of
the laptops is pretty much different (one has built-in BT, on the other I
use an external USB dongle) and they both stopped working at about the same
time. And when I boot the grml live-cd, hciconfig happily shows me the BT
device.

One of the laptops is running Ubuntu-10.10, the other one is running
Ubuntu-11.04.

Any ideas?
