I have an M-Audio MobilePre USB and have modified uaudio to upload the firmware to the device using DFU, but I don't believe these changes are responsible for the problem as they worked fine in -stable, and once the device is programmed the added code is not touched. If I use mpg123 it runs fine, but if I try artsd I get the following crash. (I tried to get a crash dump but -current doesn't see cooperative on that front at the moment..)
