There was a module called scanner for the 2.4 kernel. With the 2.6 kernel, there is no longer a scanner module.Hallo,
any time i boot up my machine the scanner will not be recognized . I have have to plug the scanner out and in and then I am able to scan. Next time i start xsane no scanner! I have to plug him again out and in and than i can scan again.
It's an USB Scanner and worked well in all Redhat and Fedora versions before, only in Fedora 2 i have to do this trick with the usb cable.
If i start usbview the scanner is recognized as a Unknown Device.
I hope i am not alone with this Problem?

Since the usbdev module needs to be used instead, the permissions get set for the USB scanner as 644 (set during system start/ hardware detection).
Also the owner of the device is root. If you tried the scanner as root, it would work. If you changed the permission of the file for the scanner as world readable 006, the scanner would work as a regular user.
The hotplug addition to the scanner program (sane-backends) was added so that the scanner can be turned on or the usb cable unplugged or unplugged to get the permissions changed to 600 for the console owner. (GUI) when the device is recognized. The device needs read/write access.
Basically, if this hotplug feature was not added, there would be a more serious problem than turning off and then back on the scanner or unseating,then reseating the USB cable to the scanner.
Check out a bug submitted by Roland during the test phase for the problem background and proposed solutions.
