Thank you!  When I looked at scan.log I discovered the problem.  It was 
really stupid, if you look below at my epson.conf you'll see it's looking for 
/dev/usb/usbscanner0
not 
/dev/usb/scanner0

My bad.  Thanks for the help though, if you hadn't mentioned the debug 
enviroment I would probably not have gotten it working for some time.
