Mind telling the EPSON engineers for me ;-)

I just checked with a Stylus Photo RX500.  Here's the output of lsusb
(with only this USB device attached) on Debian testing/unstable.

  olaf at zen:~$ lsusb
  Bus 004 Device 001: ID 0000:0000  
  Bus 004 Device 002: ID 04b8:0807 Seiko Epson Corp. 
  Bus 003 Device 001: ID 0000:0000  
  Bus 002 Device 001: ID 0000:0000  
  Bus 001 Device 001: ID 0000:0000  
  olaf at zen:~$

I guess you could also flip the ownership and use something like
lp:scanner if that would be more appropriate.
