Hello,

I've tried suspend/resume code of USB devices. Unfortunately it does not work :(

First it complains that USB device has 0 interrupts (as module was not used
since start but it was loaded)

Second I got following messages:

unlinks.  Use usb_kill_urb()

After resume it disables IRQ 11 for USB and that IRQ is shared with eth0:
