xsane don't detected canon N1220U scanner
 

I've a canon N1220U scanner and a use slackware 10, but the problem it's that the xsane don't detect the scanner. The scanner is detected in anothers distros. Do you think that slackware 10 have some kind of usb configurations to do (lique the parallel ports). Do you know athoer program for scanning...
What can I do?

Try this:
/sbin/modprobe usb-uhci
/sbin/modprobe uhci
/sbin/modprobe usb-ohci

Then: sane-find-scanner

Btw, read: man xsane and man sane maybe you can get some hint there. Oh, and what's the company that makes a N1220U ?

Have you tried xsane as root? I have a problem with my scanner. Only root recognizes it. Solution? Boot up, unplug the scanner, plug it back in. This is assuming that hotplug is working. See if that works for you.

Oh, and I also created a group "scanner" and added myself to that group.

When a I do I've got:

sane-find-scanner

found USB scanner (vendor=0x03f0, product=0x0605) at /dev/usb/scanner0

Then, /sbin/modprobe usb-ohci is the one you've to use.
Run: xsane /dev/usb/scanner0
and you're done :)

xsane /dev/usb/scanner0

give me:

Error to open the device '/dev/usb/scanner0"

Let's start from scratch, what scanner do you have? I know N1220U, but is it Epson, Cannon, HP? Also, is it usb?
Try sane-find-scanner and scanimage -L as root (the latest should give you more specific info).
