Tried exactly the version requested (v3.7-rc2-raring). It resulted unity
failing to load properly (expected, because i was using fglrx driver
which perhpas compile against my previous kernel).

Nevertheless, new kernel doesn't work. Without unity, I can still do
'hcitool scan' as root. No device is found by it.

In order to try if 'hcitool scan' in general work with the new kernel, I
put on a secondary external USB bluetooth adaptor, indending to try scan
again with that adaptor. But it resulted bluetoothd segment fault right
after USB device plugged in.

I rebooted to the old kernel and did 'hcitool -i hci1 scan', whcih uses
the external bluetooth adaptor, and I do find device, meaning the device
in test is not to be suspected.

Would you be so kind to provide a workaround? I mentioned in previous
post a commandline workaround which force use of external USB adaptor,
but in reality it works very unstable. I guess a stable workaround would
require preventing the kernel discovering the first internal bluetooth
adaptor.

P. S. If you have kernel source, have you poke in to see if the DEVICE
id in question was referred to there?
