No worries Terry. It's beginning to look like a problem in ALSA. When I look for what processes are using sound devices, I get this:
________________________________________________
fuser -fv /dev/snd/* /dev/dsp*
Specified filename /dev/dsp* does not exist.
? ? ? ? ? ? ? ? ? ? ?USER? ? ? ? PID ACCESS COMMAND
/dev/snd/controlC0:? pi? ? ? ? 23842 F.... pulseaudio
/dev/snd/controlC1:? pi? ? ? ? 23842 F.... pulseaudio
/dev/snd/controlC2:? pi? ? ? ? 23842 F.... pulseaudio
---------------------------------------------------------------------------------
These processes I can kill by PID. It doesn't help though. Here's lsusb:

The device with the arrow is the one that's inaccessible. If it's in this list, it's seen by the OS.
I'll continue working through this and post my results here.
Unless Jason has some brilliance in this.... B-)
