Problems with QNX 6.1.0

I have installed QNX 6.1.0, from the ISO, onto a Compaq Presario 5000T. The
machine contains a 1GHz Athlon (w/VIA 82C686 chipset) with 512MB of RAM and
two 40GB IDE hard drives. QNX was installed on its own 5GB partition. The
video card is an nVidia-based GeForce 2 MX/MX 400 w/32MB SDRAM. The keyboard
is a stock PS/2 keyboard, and the mouse is a Logitech USB Wheelmouse.

The system contains the following operating systems:

WinME (came with the box)
Win2K SP2 (the primary work OS)
RedHat 7.2 with various kernels
SuSE 7.3 with stock 2.4.10 kernel
BeOS 5.0.1 Pro
QNX 6.1.0 installed from ISO, downloaded from the web, and burned under Win2K

The boot manager is Grub (from RH72). All systems boot minimally from Grub,
and all but QNX boot completely.

The problem with QNX seems to be Photon. It will not come up cleanly. It does
not recognize the USB controllers on the box (keep in mind that every other OS
does, even BeOS, and BeOS hasn’t had an upgrade to speak of in nearly two
years). I have QNX configured not to start Photon on startup so that I can use
QNX for basic work, but I would like some pointers on how to properly
configure QNX to see the USB devices such as the mouse. And BTW, I did install
the Logitech as a PS/2 mouse (with a USB-to-PS/2 adapter) and even though all
other operating systems saw it and used it, QNX did not.

I keep bringing up the other OS’s in case someone want’s to flame me for
trying to run QNX on ‘broken’ or ‘poorly-conformant’ hardware (that’s the kind
of abuse I tend to get on the Linux newsgroups from time to time).

Thank you in advance.
