Here is some more output on the earlier problem

[Tom]

Sorry to post again, but any ideas on this??? It works fine on one machine but
on another it doesn't.  The only difference is that the machine on which it
works is older and has USB 1.1 ports while the newer machine has 1.1/2.0
ports...
Could that be the problem?  dmesg finds the device just fine though, and it
loads the right module (snd-audio-usb) but the alsamixer cannot connect to the
device.
