I have an Intellimouse Optical attached via a USB hub to a Windows 8.1 computer.
Sometimes when the computer wakes from suspend the mouse won't track. Both the lights (the tracking LED & the taillight) are on & the mouse buttons & scroll wheel work. I also have a trackball attached to the same USB hub & it always works fine.
The cable where it exits the mouse body shows no signs of cracks or wear. The Windows hardware manager says that this device is working properly.
Has anyone experienced this?
