I just switched my OS to linux and was wondering if anyone can help me get my "Assimilation Process" (yes that is the company name) trackball to work. I tried using it on a PC serial port just for the hell of it and it wasn't recognized (no surpirse). The Kensington W2K drivers don't work. The unit works on my Mac Plus and 512K Mac without any driver so I know it's operational. Does anyone have low level detail about this devices operation like its step resolution, communication interface and pinout?
