From the descriptions it looks like it is exactly the same problem
which occured with the AV7110 cards and networking. I described a
few months ago on this list why this problem occurs. I am not
surprised that it also happens with the USB adapters, especially
in something like the usb_start_wait_urb() function. It even can
occur (but very seldomly) with the Nova kind of cards (down() can
sleep!). I also described how to work around the problem and
this fix seems to work fine so far. I have not tried this with
any USB interfaces though.
