+This example should run on most AVRs with only little changes. No special
+hardware resources except INT0 are used. You may have to change usbconfig.h for
+different I/O pins for USB. Please note that USB D+ must be the INT0 pin, or
+at least be connected to INT0 as well.
+We assume that an LED is connected to port B bit 0. If you connect it to a
+different port or bit, change the macros below:
