[sane-devel] HP scanjet 4470c problem

[Nordine Tbahriti]

Hi,

I have a brand new HP scanjet 4470c (usb and parallel port) connected to the 
usb port and I cannot make it work. Is it supported ?


Here below is some detail:
==========================

I get the following message when I type the command:

$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
