I've just completed the installation of Slackware 10.1 on my new system and
everything has gone great (audigy 2zs, nForce audio/network, and geforce)
all work great. The odd problem that I am having is that my Microsoft
IntelliMouse Explorer 4.0A is not working properly in the console or in X.

I've used this mouse in Slack 10 before and it works great, using gpm with
the IMPS2 option. But now, the mouse responds only in the Y-Axis (but not
x-axis).

As I have switched from VIA to nVidia for the motherboard chipset I cannot
rule that out. The mouse works fine in Windows XP (dual booting).

I am using the default sata.i kernel (2.4.xx). Could USB be broken?

Any help?
