The usb system already allows for soft interrupts, but this appears to be a little better. I've not done a 4.x port, nor even bothered with supporting it. Others are welcome to tweak that part of things. I've been running these patches for a couple of months now. This should help people that have usb and network shared. Comments? Warner
