Myself, I have resorted to psmouse.proto=bare because that works and the only drawback is that the mouse wheel doesn't work. The Belkin switches are the problem. I'm too cheap to buy another brand but I probably should just bite the bullet. The 2.6 kernel obviously has timing issues which causes this to occur on the Belkin switches. I don't believe that this is a distribution or driver issue but rather a kernel issue. Whether you replace the Belkin switch with another brand or resort to one of the techniques such as psmouse.proto=bare is your choice. Craig
