So I start jackd and it runs fine for a while. Then ALSA crashes and triggers an xrun. Jackd continues to do its merry thing - minus the part about spitting info out to my soundcard...
At first I thought this was a Jackd issue but when I looked deeper it seems to be ALSA. Once this happens I cannot restart jackd and resume an audio session. In fact, I cannot even rmmod snd-usb-audio. Sometimes I cannot lsusb. So it looks like something is getting seriously hosed!
Looks like a bug in the USB controller driver, probably triggered by some unexpected behaviour of your USB controller.
When this happens, are there any error messages in the system log?
