Hi Lee, sane-backends-1.0.12 has the more current backend than sane-1.0.9.hp.1.01. But in your case it should make no difference. Please have a look at your /usr/local/etc/sane.d/hp.conf. It should have lines with
# HP ScanJet 4100C usb 0x03f0 0x0101 You can also activate the lines /dev/usb/scanner0 option connect-device if the scanner is not recognized automatically. And please check which libraries are used. The libraries at /usr/lib/sane maybe the libraries which have been installed by your RedHat distribution. And at /usr/local/lib/sane your compiled libraries may be placed.
