OK, i have to correct myself: maybe that error (EOVERFLOW) has happened
sometimes, but very rarely, and in any case it's not a problem in my
systems. Also, I don't consider resubmitting a workaround, but just the
sane thing to do in the sitation. If USB interrupts stop happening
completely (even to the USB host driver) then there's nothing qc-usb can
do. Or did you just mean that they don't happen to the pwc URB handler
anymore?
It would be interesting to see if you get this error with the qc-usb
driver too (enable debugging and use "qcset debug=errors" to see if you get
messages "isoc URB error -75, resubmitting" into your logs).
