My Expert Mouse 7 Trackball is not working. What steps can I take?
If none of the red LEDs are lit, or if the trackball is not recognized by your computer system, there are several actions you can take.
First, consider the following questions:
Does the device work on a different port? Are the red LEDs lighting up or is the device getting no power whatsoever? If no power, does the device work properly on a different USB port? If not, try the device on a different computer if one is available. Does the device work on this other computer?
Determine whether the trackball is connected properly to the USB port or the PS/2 port of the computer (remember to plug the Kensington trackball directly to the computer's port, do not connect through a hub).
If using a Windows based system, check the Device Manager for conflicts from the following path:
Start \ Control Panel \ Performance and Maintenance \ System \ Hardware \ Device Manager
[Expand Mice and Other Pointing Devices by clicking on the + symbol.]
Look for the description of the attached trackball. For example, if you have a Kensington PS/2-style mouse, it appears in the Mouse category.
Look for exclamation or question marks to the left of it (exclamation or question marks are red or yellow in color). If either of these marks appear we will need to uninstall the device entirely and allow it to be re-discovered by the system.
Look for the uninstall option on the menu. Click on 'Uninstall' then reinstall the drivers again for the device. Drivers for this product can be downloaded from this location:
Kensington Software Download Page
While still in the Device Manager look under Universal Serial Bus controllers for any unknown devices. If any are listed right click on the unknown device and uninstall the drivers and unplug and re-plug the device. Remember, do not troubleshoot the device while it is attached to a hub, connect directly to the computer's port.
Can I use a different ball in the Expert Mouse 7 Trackball?
No, the Expert Mouse 7 control ball has been designed with unique reflective qualities for optimum tracking performance. Another ball may not provide sufficient tracking details to provide a good user experience.
Is my Optical Mouse compatible with my Mac?
If it is running Mac® OS X or later with an available USB Port.
