Re: [LAD] snd-usb-audio dying on jackd xruns

Tried all the different ports I could. Seems I can't get it on the EHCI
buses no matter which ports I use. Even replugged the front USB cable to the
other ports but it always comes back on the two OHCI busses. Am thinking of
buying a separate PCIE USB card as a temporary work around... I've had to
cancel my studio sessions for the week on account of the systems being down.
ARG!
