[sane-devel] Fwd: Why will sane-find-scanner detect my scanner, but scanimage -L won't?

[Mark Drew]

Allan,

Yay!  I got the debug log you asked for (attached).  Looking through it,
the problem seemed to be:

...
> [epjitsu] do_cmd: finish
> [epjitsu] load_fw: failed to lseek file
> /usr/local/share/sane/epjitsu/1300i_0D12.nal
> [epjitsu] destroy: start
> ...


Sure enough, the file referenced in the log doesn't exist, but I knew I'd
put it there.  Turns out it was in /usr/share, not /usr/local/share.  The
thing is, my /etc/sane.d/epjitsu.conf has this in it:

# Fujitsu S1300i
> firmware /usr/share/sane/epjitsu/1300i_0D12.nal
> usb 0x04c5 0x128d


So, it looks like scanimage -L isn't honoring the setting in my config
file.  My config file said it was in /usr/share/..., but it was looking for
it in /usr/local/share/...  Or maybe, might it be using a different config
file somewhere else since I built/installed it from source?

Anyway, I soft-linked /usr/local/share/sane/epjitsu/1300i_0D12.nal
to /usr/share/sane/epjitsu/1300i_0D12.nal, and voila:

[mark at PotableLinux ~]$ scanimage -L
> device `epjitsu:libusb:002:009' is a FUJITSU ScanSnap S1300i scanner


I can scan now!

Thanks for your help and your time working on this driver!!!  I hope this
information helps you continue to improve the driver (assuming you're
working on it).
