General Description:
This file contains parts of the USB driver which can be configured and can or
must be adapted to your hardware.
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 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.
