Friends please send in ur ideas and suggestions on this... My USB mouse is working fine on my AMD64 system. Can you run grep mice /etc/X11/xorg.conf which should return Option "Device" "/dev/input/mice" What happens if you unplug the mouse and then plug it back in again? Otherwise, I'd suggest it's an oddity in the chipset: system-config-network must poke it in such a way that it detects USB. Can you run tail -f /var/log/messages (as root) and then run system-config-network (from another window), and see if anything gets added to the end of /var/log/messages? Are you fully up to date on patches? What does /sbin/lspci | grep USB return? Thanks, James. -- E-mail address: james | "A remote is a *great* thing.
