USB Support

I was curious about USB support in QNX4 / Neutrino.
After checking the state of the beta test USB support
I looked for a 3rd party solution.

SoftConnex Technologies, Inc.
responded to my request with the following:

Thank you for your interest in SoftConnex. USBLink is a
USB host stack and library of class drivers intended for the
embedded market. As such, it is not priced for direct end
user purchases. As to the question re QNX, we have licensed
our stack to them, so if you are using that RTOS it already
incorporates our code.

Am I mistaken, does the USB beta not use this solution, and
if not why not? Can anyone comment?
