Hi
I recently did a fresh install of slack 11.0 and I'm still ironing things
out. I hope this is the last request I have to make about the setup.
At present I can only use xsane as root. I had this problem under slack
10.2 until I changed permission on the correct /proc/bus/usb file. That
didn't work this time.
Also there is no /dev/usb/scanner file present, although I don't know if
there should be one or not. The only file there is /dev/usb/lp0.
Advice would be appreciated.

Try to start xsane from a terminal. Tell us what error messages you get, it
any.

As a user I get the graphic that says something like "looking for devices"
Then the graphic that says "no devices available."

As root the first graphic is the same (after the warning about using it
as root), then the scanner itself is available.

Does your username belong to the scanner group? (etc/group)

I just now added it (scanner::93:jwc) but it didn't change anything.

Did you log out and log back in after adding yourself to the group? Nothing
would change if you didn't do that.

The fact that root can use the scanner indicates that the device node does
exist. It should be a matter of identifying it and getting permission to
use it.

If you're using udev, the scanner device is created on the fly. And if you
do ls -l /dev/usb* you should get something like:

crw-rw---- 1 root root 189, 0 2006-10-29 02:13 /dev/usbdev1.1
crw-rw---- 1 root scanner 189, 10 2006-11-03 21:15 /dev/usbdev1.11
crw-rw---- 1 root root 442, 10 2006-11-03 21:15 /dev/usbdev1.11_ep00
crw-rw---- 1 root root 442, 10 2006-11-03 21:15 /dev/usbdev1.11_ep02
crw-rw---- 1 root root 442, 10 2006-11-03 21:15 /dev/usbdev1.11_ep81
crw-rw---- 1 root root 442, 10 2006-11-03 21:15 /dev/usbdev1.11_ep83
crw-rw---- 1 root root 442, 0 2006-10-29 02:13 /dev/usbdev1.1_ep00
crw-rw---- 1 root root 442, 0 2006-10-29 02:13 /dev/usbdev1.1_ep81
crw-rw---- 1 root root 189, 128 2006-10-29 02:13 /dev/usbdev2.1
<snip>

Notice that the second node belongs to the scanner group, with read/write
permissions. I think you should see something very similar - some node
that belongs to a group other than root.

If you're _not_ using udev, then I _think_ your scanner is going to
be /dev/usb/scanner0 (or /dev/usb/scanner1, etc). Match up your group
membership to it's ownership.

Don't forget to logout and login again.

Ok, That finally did it! Much obliged.
The next post on my PAN list is my post about the trouble I'm having
printing graphics files. Why don't you have a go at that one too.
Thanks, jwc

Good! Had my fingers crossed on that.

I have been thinking about it. I'll put my ideas in that thread.
