Enabling "SCO (voice) support" under Device Drivers --> Networking
support --> Bluetooth support --> Bluetooth device drivers --> HCI USB
driver causes the same error for me, after disabling SCO everything
works ok. The SCO really is the root of all evil, you know... ;-)

And this is with my desktop box: AMD Athlon XP 2400+ and Asus A7V-133
motherboard, with some USB bluetooth dongle made by SCM.

I hope this little piece of information helps you.
