Just one bluetooth mouse.

I'll attach the plain text file will most of the output requested by
/usr/src/linux/REPORTING-BUGS
the outpu of DMESG from after booting to recover from the Oops is at the bottom.

Thanks for your test.
Unfortunatly, hidd device is the child of hci conn device as well, so
it should not be moved to NULL.
This is my lost, I will send this patch again later.
But there's still a hidden weird bug when we move the device while
suspend/resume, I will continue to debug the issue.
