I do not have enough knowledge of Linux to answer those questions. I am
running Ubuntu desktop the GUI version so I must be running some nVidia
driver. I run the GUI version so I can poke around faster. I have spent
most of three weeks getting this far. I will continue to work on this
but need to be pointed in the right direction. I have another project
that needs most my attention for the next week(spec. for a fire truck
for my volunteer fire department) but will work on this in my spare time.

Two things:
1) Can you reproduce this if you disable SMP?
2) Do I read this right that it still happens without the nVidia
binary driver loaded?
If either of the above is true, then you have a case for a bug in the
Linux USB stack.
Nothing that we do from userspace should cause a kernel page fault.
