Hi Christian,
I haven't tested PyUSB in a multi-thread environment yet, but you could try
run your script with python interpreter running into gdb, so you can stop it
and see
traceback to find out where the program is stalling...

PS: I have a little test board to PyUSB, so I think that I could use it
to test your code..
