[STR New]

If you send a job to an unplugged usb printer on linux, the process called
usb takes 100% of cpu usage.
It happens, as far as I can see, due to an infinite loop in usb-unix.c.
If no device returns EBUSY, sleep() is never called.
The attached patch fixes this issue here. Please, check if it can be
applied upstream and if there are no side-effects.

Thank you
