- Three tactile switches

NOTE: I see that Sure Electronics shows both of these boards at end-of-Life
(EOL). So I assume that these boards will no longer be generally available.
This work should still be useful, however, for other PIC32MX4-based boards
(2012-5-27).

NOTE: Using the SYSLOG to get debug output has limitations. Among
those are that you cannot get debug output from interrupt handlers.
So, in particularly, debug output is not a useful way to debug the
USB device controller driver. Instead, use the USB monitor with
USB debug off and USB trance on (see below).
5. Enabling USB monitor SYSLOG output. If tracing is enabled, the USB
device will save encoded trace output in in-memory buffer; if the
USB monitor is enabled, that trace buffer will be periodically
emptied and dumped to the system logging device (UART2 in this
