Hello,

it's been many years since I last tried to make a mouse work in QNX4.25.

But as far as I remember I used to do this:

-check if IRQ12 is not shared
- run Mouse/Input in very verbose mode (like five -v) and try to capture type of mouse it detects (PNPsomething)
- then try to add this string to /etc/pnpmouse (or something similar)
- if it's there, try to change given mouse type to some other
- for test if it works fine use Mouse test

Hope it helps,

PKY
