    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.

    Regards

    Marcel
