When I tried to upgrade via DVD I had numerous problems and most of them were fixed by installing with automatic configuration.
My laptop is a Pavilion dv2000.
I added on the bluetooth 2.1 Internal module and it worked perfect in 11.2.
Anyway, bluez won’t start and the bluetooth hardware is not recognized by USB.
My laptop doesn’t have bluetooth so I can’t give a direct answer. I do think you’d get more response on the wireless sub-forum and try adding more information such as which desktop you’re using, what steps you have taken to isolate the problem, what driver it’s trying to use, etc.
