I was using Vista Ultimate 32bit with this Dell system with PS/2 mouse.
I bought a new USB mouse to replace the broken mouse.
But when power up Vista, it does not recognize this new USB mouse.

I check this USB mouse at my laptop, and this mouse works fine.

How can I make Vista to switch from PS/2 to USB mouse?
Thank you.

This shouldn't affect things, but you never know, - is legacy USB
support enabled in the BIOS? Did your USB mouse come with a
USB to PS/2 adapter you can try?
