FYI..  Problem is not limited to the printer. Also found same problem with a 
GemPlus smartcard reader that will not poll until unplugged and replugged in 
after reboot.

Found something interesting. If you add a USB hub between the PC and the 
devices that are not recognised on boot up, they will be polled correctly 
after reboot.
