Karl and Others:
I went back over this log and discovered that the file epson.conf file
had an incorrect entry . I changed the enty from "/dev/usb/scanner0" to
"usb /dev/usb/scanner0" as I had been instructed. Thanks for your
assistance and patience. Scanner seem to be working correctly and I
have it working with gimp. One last question. Where do I get
information with regards to linux drivers for my HP 970Cxi printer? I
am not at all happy with the print quality.
Again thank you very much.
