Note: The use of a single array
usbs_testing_endpoints
limits USB testing to platforms with a single USB
device: if there were multiple devices, each defining their own instance of this array, then there would a collision
at link time. In practice this should not be a major problem since typical USB peripherals only interact with a
single host machine via a single slave port. In addition, even if a peripheral did have multiple slave ports the
current USB testing code would not support this since it would not know which port to use.
