2005 PowerBook G4 Special Report: Kensington USB trackball issue
There is a connectivity issue with some external, USB trackballs manufactured by Kensington when used in conjunction with Apple's 2005 PowerBook G4 systems.
Some users have been able to overcome this problem by using the shareware utility USB Overdrive as an alternative driver:
"One of the replies mentioned getting USB Overdrive to use instead. I downloaded it and started it. The second (!) that it loaded, the MouseWorks icon appeared in the menu bar. A dropdown from that took me to the MouseWorks preferences where I could finally program the buttons. The gamble was deciding to remove the USB Overdrive program and see if I would then lose the connection to MouseWorks."

external keyboard with the help of Kensington Docking Station. I bought a
new USB Kensington trackball (Turbo Mouse wireless), and it worked fine for a
couple of weeks. Now, though, it's stopped working. The trackball does not
move the cursor and none of the buttons work, although when I go under
system prefs > mouseworks and click "about" > devices, my turbo mouse
wireless shows up.
A pretty much inscrutable Kensington service rep said he would send me a
new trackball, after almost no inquiries and no suggestions for
troubleshooting, other than "have you cleaned the trackball"? But I suspect a
software conflict.
Any suggestions? I am running Mouseworks 2.51.
