- Subject: Reset ADB -- Fix 'frozen trackball' problem
-
- This program, which I wrote quite some time ago, fixes a problem I
- understand was somewhat common to people with multiple devices on
- their ADB ports.
-
- Sometimes, when the Mac is booted, the mouse, trackball, or keyboard
- (sometimes two of the three, rarely all three) refused to work. At
- first, my only recourse was to reboot the machine. Finally, while
- playing with Think Reference (An excellent _Inside Mac_ -style utility
- from Symantec), I found out about the ResetADB system call. So, I
- wrote a tiny program to call this function, which reset the ADB,
- reloading the device driver for the trackball.
-
- Two caveats: I have since found out that resetting the ADB is a _BAD
- THING_ on some older SE machines, which had a bug in their ROMs
- relating to the ADB. The system patched it, but after the bus was
- reset, the patch was cleared...
-
- Also, you might ask how one could launch this program if the mouse (or
- trackball, or both) didn't work. Answers: FinderKeys (or something)
- in System 6 from Now Utilities 2.x (or so I'm told)and System 7.x.x
- both give you the ability to make a selection via the keyboard. So,
- use the arrow keys to select it, & hit command-O.
-
- This program is freeware. Share and Enjoy. All I ask is that if you
- find it useful, try to let me know. Redistribution is allowed, as
- long as I am credited. All rights reserved. This product has no
- warranty, and much disclaimer. I hope you never need it. But if you
- do, here it is.
-
- One last point: The icon took longer to design than the program did
- to write. Funny, eh?
