FC2,Gimp & scanner problems


Since installing FC2 I have been unable to access my Canon FBU30 scanner. The device is recognised as root (but won't run), but not as a user.

Any suggestions?

Thanks

To set up the scanner, you need to look at sane, and possibly its xsane front-end.

Go to http://www.sane-project.org and follow the instructions…

If root can see the device but regular users can't then there may be a permissions problem. But one needs more information on what you are doing to verify that on root can “see” the device, such as actual error messages.

I know its a permissions problem. I did some commands I didn't understand at all mentioned in "Bug 121511 - extend console_perms to cover -proc-bus-usb-" at bugzilla. For one session I was actually able to use the scanner as a user, but not since. I have no idea what the sequence of commands were.

In that same bug report forum, they mentioned SANE-Backends-1.0.14 having a script which solves this situation, but I have not been able to locate an rpm for this and would not have the skills/confidence to install without rpm at this stage.

Thanks for your input

sane package RPMS: Have you tried http://www.rpmfind.net ? You will find a link at http://www.sane-project.org/source.html under the “binaries” section.

If/once you have installed sane, you should have a script called sane-find-scanner. Open a terminal, and type
Code:
sane-find-scanner
. What is the output of this script?

Device information? Sane-find-scanner has limitations.

I've been having problems with my UMAX-600L parallel port scanner and found last week that sane-find-scanner does not work to discover parallel port devices.

Rjlee, you should include some explicit description of your device type to save the rest of us from scratching our own heads unproductively.

Sorry. My device is a USB Canon CanoScan LiDE 30 (which is detected fine). I didn't mention that before because I didn't think a particularly helpful piece of information.

What I'm trying to find out is why gchandler thinks his scanner can be detected as root (which persumably means it will show up on sane-find-scanner, especially since it's USB which tends to handle autodetection very well), but not for other users.

After much further mucking around, the error I now get when trying to use scannner in Gimp is "device busy". If I tick the calibrate scanner box, it does try to do something with the scanner, but then nothing

Sorry abou the delay in responding - unwell...
