Well, that should be exactly what happens when you put the cover on,
with the possible exception that btcond will also try to disconnect any
open connetions. So you may also want to try
hcitool dc <remote bt address>
before running the hcitool hci0 down command. Also make sure that you
are root when running the commands.

Unfortunately not, but it sounds like a quite low level problem (maybe
in the BT chip firmware). However, we're investigating it.
