Two machines: 1. Winblows Fiesta (all works fine) 2. Ubuntu 8.04 (mouse movement is delayed, skips, slow. Keyboard skips keystrokes often at reguar typing speed. They both work fine when plugged directly and not using the KVM switch) Belkin flip KVM switch. These are the relevant config files and inqueries: "lsusb" comand output /etc/x11/xorg.conf "dmesg | grep usb" command /var/log/syslog /etc/modules THANKS IN ADVANCE FOR ANY HELP.
