This document applies to older computers running MS-DOS and not a Windows command line having trouble getting a USB mouse to work in the Windows command line.

Computer Mouse

For the mouse to work in an MS-DOS environment, you must have the Microsoft mouse driver mouse.com loading in your autoexec.bat file or the mouse device driver mouse.sys loading in your config.sys file.

Find the MS-DOS mouse driver

Before placing any information into the Autoexec.bat and Config.sys, you need to locate one of those files on your computer. To locate a file in MS-DOS, type either of the commands below at C:\> prompt.

dir mouse.com /s

or

dir mouse.sys /s

Once either of these commands are typed in, you should receive a listing of what directory contains one of the above files. If you get a file not found error, try the alternate command.

Load mouse driver

Once the file is located on the computer, follow the instructions below that correspond with the file that was found.

Autoexec.bat

LH C:\Windows\MOUSE.COM

Config.sys

DEVICE=C:\Windows\MOUSE.SYS

The above two lines are examples; if either file is located in another directory, you would need to substitute the C:\Windows\ for the directory containing the file.
