I recently upgraded my dual boot Pentium 4 machine running XP and Redhat Linux to Redhat 9. Success, but my new printer and scanner and modem which are USB powered and are not configured properly. I have an Epson 640U scanner and XSane gives me an error saying that the device is not recognized. I already know I need to modify the usr/lib/? files and probably change permissions somehow along with some front-ends/back-ends/makefiles. I don't know but it all sounds complicated and when I search the web for help the results are hard for me to follow. The printer is a Dell A940. It's a new one. But surprisingly, it was detected on start-up. I'm a fast learner but would like to know if there is a primer available for writing bash commands as root to make all these peripherals work nice together. Hate to be a pain but this has been alot of trial and error leaving me frustrated.
