PS/2 keyboard won't work with USB mouse

[Jeff Bradberry <jbradbe2@iusb.edu>]

I've just purchased a Logitech USB Optical mouse to replace my old PS/2
Logitech Mouseman Plus.  I've set up USB with no real problems, and the
mouse and keyboard coexist fine on the console.  However, when I get into
Xwindows, the mouse works fine but the keyboard does nothing whatsoever.  
When I exit X, the keyboard works fine again.  I am running
xserver-xfree86 version 4.1.0-17.  Anybody have any ideas why this would
be happening?
