Problem with Notebook Optical Mouse

[Jacques Fournier]

I run Fedora Core 1 (with all updates) on a Toshiba Satellite Serie 5100 
Laptop.  Everything goes fine, except one thing (I won't qualify that 
thing!):  I cannot use my USB optical mouse, a standard two buttons and 
one wheel usb mouse!

The Toshiba also use a Touchpad, which is working perfectly.  The 
problem is that I cannot plug in my usb mouse and use it!  The Touchpad 
is not as convenient as a mous to use!

How can I configure the mouse to run?

Thanks for help.
