if I am not mistaken, then this is a CSR based dongle. Would need to
decode the Rev=43.15 into the build id. However an easier way is when
you boot into Windows first and then into Linux so the dongle works and
then execute bccmd buildname (as root).

You could sniff the init sequence under Windows. Would help to find the
init sequence.
