Thanks again for the help. I now have a BT500. (They are hard to find as
Amzo and BH Photo are out of stock I see that FreeBSD detects it as a
Realtek ASUS BT500. I get the following messages:
Jan 17 13:32:06 ptavv kernel: ugen0.5: <Realtek ASUS USB-BT500> at usbus0
Jan 17 13:32:06 ptavv kernel: ubt0 on uhub0
Jan 17 13:32:06 ptavv kernel: ubt0: <Bluetooth Radio> on usbus0
Jan 17 13:32:06 ptavv kernel: WARNING: attempt to domain_add(bluetooth)
after domainfinalize()
Jan 17 13:32:06 ptavv kernel: WARNING: attempt to domain_add(netgraph)
after domainfinalize()

No idea what those last two lines mean, but it's not good. No indication of
fw load, though I don't know that it is required. In any case, no ubt or
bluetooth device is created in /dev. both ng_ubt and bluetooth drivers are
built into the kernel.

Am I missing anything obvious? Any ideas about those two warnings? I
suspect that they indicate my issue.

Thanks again.
