I captured a bit of debugging info from my syslog after my most recent usb-audio crash. I wasn't even near my computer at the time it occurred (in a different room via bluetooth for many minutes). The bluetooth connection simply broke (that is, probably something with my usb subsystem broke), and I wasn't able to recover from the bug. I was forced to reboot. http://dennisn.dyndns.org/guest/pubstuff/debug-usbaudio/crash1.log ------------------------------------------------------------------------------ CenturyLink Cloud: The Leader in Enterprise Cloud Services.
