QNX USB Mass Storage (Stick) support

A customer of mine has found that some USB sticks don’t seem to work right under QNX. They work on Windows. The distinguishing characteristic seems to be that while sticks that have 3 end points 0) Control 1) Bulk/IN 2) Bulk/OUT, the ones that don’t work only have two end points, 0) Control 1) Bulk/IN 1) Bulk/OUT.

They are using QNX 6.4.1. Does anyone know any more about this? Has QNX fixed this in a later version?
