" If the function succeeds, the completion handler of the urb (as
specified by the complete function pointer) is called exactly once
when the urb is completed. When this function is called, the USB core
is finished with the URB, and control of it is now returned to the
device driver."

Bingo! Because the driver will only submit *one* urb at a time,
how could it possible have more than one completion handlers
called at a time?

how about multi-thread try to send urbs on the same pipe with the same
complete function?

I wasn't thinking with the right half of my brain.
Thanks,
Ezequiel.
