I have the following configuration:

Knoppix 3.6, installed to the HD.
2.4.27 kernel
KDE

Everything has been fine with my old PS/2 mouse.

I purchased a Logitech Mini Optical Mouse, connected to the single USB port on my PC. Rebooted (multiple times). It's completely inoperative. All I can do is plug the old PS/2 mouse back in and force a reboot.

Here's a snippet from dmesg, in case that gives any clues:

Same mouse works fine booting to Win 98SE on the same PC.

What am I missing ?

Thanks !
