If you are having a problem with your mouse, you may see one of the following error messages:
8601 AUXILIARY DEVICE FAILURE
8602 AUXILIARY DEVICE FAILURE
8603 AUXILIARY DEVICE FAILURE
If you see one of these messages, make sure that your mouse is completely connected to its port on the back of the computer.
Also, be sure that you have connected it to the correct port. For example, you may have connected the mouse to the keyboard connector instead of the mouse connector. Even though the mouse connector fits into the keyboard port, you cannot use that port to run your mouse.
If the mouse seems to be connected properly, check the documentation that came with your mouse to see if there are any special procedures you need to perform to use the mouse with your computer. Also check for troubleshooting information in the documentation or contact your dealer.
