General Description:
This file is an example configuration (with inline documentation) for the USB
-driver. It configures AVR-USB for an ATMega8 with USB D+ connected to Port D
-bit 2 (which is also hardware interrupt 0) and USB D- to Port D bit 0. You may
-wire the lines to any other port, as long as D- is on bit 0 and D+ is also
-wired to INT0.
-To create your own usbconfig.h file, copy this file to the directory
-containing "usbdrv" (that is your project firmware source directory) and
-rename it to "usbconfig.h". Then edit it accordingly.
