I just recently installed Ubuntu Desktop 11.10 on my laptop.
The laptop is a Toshiba Satellite m645. It does not have a Bluetooth radio in it so I plugged in an IO gear USB Bluetooth adapter. The model is GBU421 and upon further inquiry I found out that the radio is a Broadcomm BCM2046b1.
I have discovered that
lsusb shows the radio as being found in the computer - but the Gnome Bluetooth manager says that there is nothing there. So I am guessing it is a problem with Gnome Bluetooth manager not with Linux in general.
Is there anything I can try in order to make this work?
