Hi.
I just wanted to point out that this has been the case in v6.1 and 6.2
(don’t know about 6.2.1) but I still can’t get the PS2 mouse to work.
I have tried a few PS2 mouse’es (or is it mice) but none worked. I
tried the OS on a faster machine that had USB and then the mouse
worked 
I think the QNX team need to take a look at this and fix it.
It’s not good if the two primary input devices don’t work
