USB: Host test application

There are three sets of tests in this application:

  1. Low-speed: Expects low-speed USB mouse with interrupt endpoint to be connected
  2. Full-speed: Expects full-speed USB flash disk with 2 bulk endpoints to be connected
  3. High-speed: Expects high-speed USB flash disk with 2 bulk endpoints to be connected

For running these tests locally, you will have to update device definitions (VID, PID, ...) in dev_msc.c, dev_hid.c and dev_isoc.c.
