I've just built a new system. I want to dualboot with Win XP and Ubuntu. So I've just installed Win XP (I haven't installed ubuntu yet), and my mouse doesn't work. I have tried two mice, and no one works (they're both USB). Then I noticed in SETUP, under Integrated Peripherals, an option: "USB mouse support", that was disabled. I enabled it, but the mouse still doesn't work. Every other USB device works (keyboard, USB storage devices etc.)
Any Ideas? Do I need to reinstall Win XP?
My mobo: Gigabyte GA MA790GPT-UD3H

BTW, The two different mice I tried, Logitech MX400 and a cheap atech notebook mouse, both works on my laptop, so I'm positive it's not a problem with the mouse.
New update: I tried ubuntu from the CD, and there the mouse works...
