I have the same problem. I have a Toshiba Satellite U400-12p. I installed Ubuntu 9.04 after I got sick of Windows Vista and Windows 7 with all their bluescreens. Now I have upgraded to 9.10, both versions worked great, the only problem I have had is that in both versions, the Bluetooth did not work. Ubuntu did not detect the internal bluetooth device, although it works perfectly with any other external device. Can anyone help?
