Maybe plugging in your (home) scanner confused the kernel. Do you get any messages from the USB system in /var/log/messages when you plug-in the scanner? > I'm totally confused now.

Or your distribution found the scanner and used some hotplugging magic but failed. And that stops your scanner from beeing detected again. But that's not easy to diagnose from remote. > USB-devices are hot-pluggable, aren't they?! Yes. > Could I have destroyed the scanners by unplugging them while the > pc was running?? No. I don'tt day it's not edefective but if it is, it's not because you unplugged it. I'm doing that all the day with my USb scanners and that's the whole idea of USB. bye, Henning
