Disconnecting all external devices (except VGA monitor and USB keyboard) did not make a difference, although it seemed likely that the usb audio interface was too power hungry (500 mA according to usbdevs). Updating to -current did not help either. Currently I'm trying Debian, so far I haven't been able to trigger a disconnection. Best, --- Erwin
