I reinstalled OS X following "Type 11" method to a T. I enabled bluetooth before shutting down Ubuntu, installed OS X, updated to 10.5.5, ran miniscript and rebooted. Bluetooth was working. Went to pair my HTC touch, selected device, typed in password, computer reports new PAN (Personal Area Network) Connection. Close pairing wizard and bluetooth power turns off! Have rebooted with -f -v, repaired permissions, disabled/enabled bluetooth in BIOS -- out of ideas at this point! Thanks for all your help!
