On running aplay, dmesg lists "usb 1-1: control timeout on ep0in", and thats it.
alsamixer also locks hard (kill -9 doesnt work).
The only way to recover is pull the USB cable, at which point alsamixer/aplay returns to bash.
BTW, if the USB "soundcard" is plugged in on boot, booting fails (not sure where yet).
Should i be asking about this on the linux-usb-devel mailinglist?
Thanks.
