A friend of mine has a HP 6710b (if i remember the model name correctly). Bluetooth wasn’t working. Nada… not even a USB device showing up in lsusb for the inbuilt bluetooth.
It turns out, if you disable the bluetooth radio from the Windows thingy, it does something you cannot undo from Linux (at least with Ubuntu Gutsy) .
Except… after hours of fucking around, we reset the BIOS to default settings and this made it work.
Yep, no option in the BIOS setup to do this (there’s an Enable/Disable switch… but that doesn’t fix this problem). But a reset does it.
I really hope this saves somebody else the hours of “fun” we had.
