[sane-devel] ScanJet 4100C

[Peter Kirchgessner]

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.

Sincerely

Peter
