USB DDK for qnx 4.25

I had download QNX4 Driver Development Kit for USB in following website: … s&cat=3964

I has problem generate executable devu-mouse from the source-code which saying that it can’t found, and other .mk

My question is how to get those .mk for qnx4? I don’t found it in usr/include/mk

I could only found those .mk form qnx6 only.

Currently, I am writing driver for usb joystick. Any advice is welcome.
