Problems with Bluetooth audio on the NSLU2

[Donald T Hayford <don%donhayford.com@localhost>]

Don't know if this is an NSLU2 problem, a Bluetooth problem, or a 
personal problem, so I'll start here and work my way up the ladder.

I'm trying to get Bluetooth audio to work on my Linksys NSLU2 (evbarm).  
My setup is a USB hub with hard drive plugged into the top NSLU2 USB 
port, and the Bluetooth USB adapter plugged into the second NSLU2 USB 
port.  The Bluetooth dongle is a Zoom Bluetooth USB Adapter Model 43108.

I'm using the following config file for the kernel.

include "arch/evbarm/conf/NSLU2"
ubt* at uhub? port ?
bthub* at ubt?
bthidev* at bthub?
btsco* at bthub?
audio* at btsco?
uaudio*    at uhub? port ? configuration ?
audio*    at uaudio?
config netbsd-bt-sd1 root on sd1a type ffs

If I plug in a USB audio dongle, I can use madplay to play audio through 
the dongle using /dev/audio with no problem.
When I switch to the Bluetooth dongle, or reboot with the Bluetooth 
dongle, I can follow the instructions in the NetBSD chapter on 
Bluetooth, up to a point, but madplay can't find the audio device. 

Here is what is spit out on the main console during bootup and while 
installing the Bluetooth headset.  I removed everything that didn't 
pertain to USB or Bluetooth.

btconfig=YES

On the command line, I entered the following.

-bash-3.2$ btconfig ubt0 inquiry
Device Discovery from device: ubt0 .... 1 response

-bash-3.2$ btpin -d ubt0 -a headset -p 0000

-bash-3.2$ btdevctl -d ubt0 -a headset -s HSET -A
btdevctl: /dev/bthub: Permission denied

-bash-3.2$ sudo btdevctl -d ubt0 -a headset -s HSET -A

When I run the bthset command that is in the NetBSD manual, I get an 
error (no option -d), but the following almost works:

-bash-3.2$ bthset -m /dev/mixer0 -v
Headset Info:
       mixer: /dev/mixer0

       channel: 2
       vgs.dev: 0, vgm.dev: 1

Oddly, the program doesn't exit cleanly, and I have to hit <ctl-c> to 
break out of it.

-bash-3.2$ ls -la /dev | grep audio

I'm out of ideas and Google pages.  Any help is, as always, greatly 
appreciated.
