The lab 2 code is an HID 1.0 compliant device (a keyboard), which has an
interrupt IN enpoint (EP1 IN) that is used to send the input report every
10 ms or so. There is no interrupt OUT endpoint, though it would not be
hard to add one. Output and feature reports in HID 1.0 devices are sent
via the class request SET_REPORT through EP0.
