I'm hoping there's someone on here with experience with the CSR
chipset.  This doesn't relate to BlueZ exactly, but I'm working from
BlueZ code so I figure someone here might have a clue what I'm doing
wrong.

I've been working on porting bluez's bdaddr utility to mac, and I
think I'm making pretty good progress.  After digging around the
internals of IOBluetooth.framework, I've managed to, I think,
replicate the behavior of bdaddr's csr_write_bd_addr and
csr_reset_device.

The reset appears to be working, however the write address command is
producing a response packet with a status of 0x0009, not 0x0000 as
csr_write_bd_addr seems to check for.  here's the low-level HCI
transaction dump:

HCIc: 00 fc 19 c2 02 00 0c 00 11 47 03 70 00 00 01 00
      04 00 00 00 cb 00 00 16 1b 00 7e ad
HCIe:  ff 19 c2 01 00 0c 00 11 47 03 70 09 00 01 00 04
      00 00 00 cb 00 00 16 1b 00 7e ad

as far as I can tell, the command sent matches exactly what
csr_write_bd_addr would have sent with transient=false and addr =
00-16-cb-1b-7e-ad.  Anyone see what I'm doing wrong?  Or even any clue
what status 0x0009 is?
