Do you have USBMOUSE.SYS on your config.sys ?
Hi Martin,
Well my curiosity got the better of me and I went back and tried this :-)
Thanks for the second link to the IBM USB Mouse drivers - I didn't have those. I installed those, verified that usbmouse.sys was in my config.sys, and rebooted.
This time the mouse lit-up and I could see it move on screen - hooray!
Well... not quite. Unfortunately the pointer would only move up and down, it would not move left or right!
Perhaps with more tinkering I could get it to work but I think I'll keep trying to track down a new-in-box optical IntelliMouse (PS/2 connection) :-)
Thanks anyway for the tip - I really appreciate it!
Best,
Richard.
