USB Mouse Failure?

On my Advent 9117 Laptop I have been using a Belkin USB Mouse (wired), and a Verbatim USB wireless mouse for manyn months.

Two days ago both failed and I am no having to cope with the rubbish design of a touch pad (that scrolls the screen whenever I try to move the mouse into a different position line on a page or box in an Excel table).

The Control Box - Mouse information tells me I have a PS2 Mouse and that it is working properly!

Any ideas on what has gone wrong?
