Xsane scanner found, but GUI does not find device

[tarahmarie]

I can find the HP Office Jet 6500 scanner using sane-find-scanner as you can see below, but sudo xsane finds no devices.

What am I doing wrong?

I have the exact same problem, will update if I find a fix.

ok got the scanner working. this is what I did:
run the following command as root:

/etc/init.d/udev restart

this will ensure that your ubuntu knows where the scanner is plugged in.

now xsane still doesn't work, but GIMP that I tried earlier without success is now scanning through it's SANE backend without any problems.

hope this helps

run sane-find-scanner or scanimage -L without root access and see if it sees it

just to add more info, running

sane-find-scanner

as a normal user finds the scanner, but it appears that

xsane

has a problem with GTK
