[sane-devel] HP ScanJet 3670 not working under Fedora14

[KasperH]

my HP ScanJet 3670 is not working under Fedora14. It used to work,
when I was running WinXP on the same hardware. It is still working
fine connected to my WinXP laptop's

troubleshooting I've done so far:

[root at fedje ~]# yum list installed | grep -i sane

in /etc/sane.d/genesys.conf
# Hewlett Packard ScanJet 3670c/3690c
usb 0x03f0 0x1405

So all usb tools tell me, it is there, and it can be communicated with
(serial#, pwr,)
Is sane-find-scanner(1) not sure, why is the question mark (chip=GL646_HP?)
scanimage -L   does not detect it

someone a clue why I cannot use this supported and working scanner
under Fedora 14?

Thanks for your time
