Ahh, that worked. It also apparantly lets me access channels 3 and 4! Unfortunately, I can't keep it running long enough to play with it. Jackd exits after a short time, at the same time that usb_submit_urb() returns -11, on line 199 of usbusx2yaudio.c. Running jackd again after it's given that error seems to pretty consistantly hang my system completely. Is there any more advanced debugging I can do to try to track down the problem? -spencer On Sun, Feb 27, 2005 at 12:15:33PM +0000, Rui Nuno Capela wrote: > > The rawusb support is only available if you load the snd-usb-usx2y module > with nrpacks=1.
