I've been trying to use an optical mouse on my C3600 workstation, it will work for a period of time.
The problem I'm having is, the optical light turns off and the mouse will not respond.
I can get it working by switching USB ports or by rebooting the workstation.
My OS is, HP-UX B.11.11 U
I suspected it might be driver related but have not been able to find a driver yet.
