Config/... as my earlier message on USB - though with the bandwidth enforcement
turned off so it actually plays sound, when plugged into the USB1 port.


Basically - playing sound with
mplayer -ao alsa:device=hw=1 or whatever - and then unplugging the
soundcard completely wedges lsusb/usb configuration, until the mplayer process is killed.

cat /proc/bus/usb/devices stalls.
