00007  *  Program to test the UsbHid with HidTest.java
00008  *  Java files in USBHID bindings page
00009  *
00010  *  This test program is allways sending a non blocking message and expecting to read a non blocking message
00011  *  Messages are sent with the last byte cycling through '0'-'9' and LED4 toggles with each send
00012  *  When a messsage is received:
00013  *    LED2 toggles
00014  *    Received message is sent, blocking.
00015  *    A message is read blocking
00016  *    The recived message is now the new non blocking message to be sent
