I think we actually have a broken user space in this case. I do have a
hunch on what went wrong. It is not the kernel's fault here.

If I am anywhere right, then bluetoothd fails to bring up the device.
That is why you don't see anything with "hcitool dev", but the device
should be present. Check "hciconfig -a".

Check your bluetoothd startup line and add "-P mgmtops". That will
disable the broken plugin.
