Dear Fernando 1:
Thanks for the clarification.
I do not know which steps I need to perform to accomplish that which you have written.
Installation of XP Pro has completed.
My motherboard has only 1 PS2 port. During XP installation I had a keyboard connected via PS2.
After setup completed, I shutdown the computer; switched from keyboard to mouse, installed the chipset drivers.
To add the chipset's USB drivers, which drivers would I select?
Thanks for your help.
