Can you either point to or provide sources for the linux version of libosbdm you are using?  As far as I can tell, Freescale supplies Windows DLL code and others have made necessary patches to compile under linux.  My suspicion about usbfs may have been a red herring, as adding some printfs to the linux port of libosbdm finds the device, so queries for the VID/PID seem to be fine.  See printf output below.

Not sure I can research much more without violating the EULA.
