Macintosh Apple Desktop Bus Device ID Numbers (5/95)


I just got a new keyboard and trackball for my Macintosh computer. These devices came with installation software. I am supposed to enter the Apple Desktop Bus (ADB) device ID number for my keyboard and mouse, but I cannot find this information anywhere in the User's Guide that came with my Macintosh computer. What are the ADB ID numbers?

Some third party vendors of ADB devices use software that ask the user for the ADB ID numbers of the keyboard and mouse.

Keyboard
--------
On all Macintosh computers the primary keyboard (including built in keyboards for PowerBooks) is ADB device 2.

Pointing Device
---------------
The primary pointing device (whether it is a mouse, a trackball, or a trackpad) is ADB device 3.
