It is possible that the mouse or trackball could have failed?
Verify that you have not made any changes to the system that might coincide with the failure of the product. For example, if you moved the connection of the device to another port to add another device to the system or if you added new software or made other system changes. Also, verify the device has not become disconnected from the system by checking to see the device is correctly connected. Once you have verified the above potential causes for failure, proceed to the following steps.
- Check to see if you are experiencing a detection issue.
- If you have another USB port, try that other port. If you were connected through a hub, try connecting directly to the system ports to verify the hub has not failed.
- If the device doesn't work on a second port, try it on a second system, if possible. If it fails on a second system, then the device probably is defective. You may also want to try a second mouse in the same port that the failed mouse was using.
- If the second mouse does not function in the same port, verify the system port has not failed. Contact the system manufacture for more information on the status of the system port.
- If either the mouse fails on a second system or the second mouse works in the same port, then you know the Toshiba mouse is defective. If this is the case, please contact the Toshiba customer service.
