I'm looking for feedback on how to troubleshoot why inserting a USB data device causes a QNX 6.3.2 system to lock up. 
(Advantech systems are in use)

I'm somewhat certain it is not directly OS related as the behavior does not repeat itself inside of a virtual machine. 
Searching around finds a backport of QNX 6.5 USB drivers for similar reasons. 

Any clues/ideas/brainstorms/and flames are appreciated.
