Hello,
don't know if I need to report my problem in alsa-dev list for the driver
or linux-dev list for the usb interface, please correct me if I post in
wrong mailing.
sometimes, my USB audio device disappears from the system, the only way to
make it appears again is to disconnect/reconnect the usb wire.
Here are the traces I took :
USB DAC suddenly disappears, from dmesg I can see:

from "aplay -l" the card is seen as :

after disconnected/reconnected the usb wire:

Is there any debug i could turn on to get more informations?
