The right way to fix this is to add reset_resume to the printer driver.  

More generally, usbcore should be changed so that drivers which don't 
support reset_resume get unbound from their devices when a reset-resume 
occurs.  I wrote something to do that last year, but with all the 
changes going on in the driver core it is now obsolete.
