*
* Mouse demonstration application, using endpoint interrupts for the
* exchange of data to the USB host, and control requests on the control
* endpoint. This gives a simple reference application for implementing a
* USB Mouse using the basic USB HID drivers in all modern OSes (i.e. no
* special drivers required). It is boot protocol compatible, and thus works
* under compatible BIOS as if it was a native mouse (e.g. PS/2).
*
* On startup the system will automatically enumerate and function
* as a mouse when the USB connection to a host is present. To use
* the mouse, move the joystick to move the pointer, and push the
* joystick inwards to simulate a left-button click. The HWB serves as
* the right mouse button.

# This will define a symbol, F_CPU, in all source code files equal to the
# processor frequency. You can then use this symbol in your source code to
# calculate timings. Do NOT tack on a 'UL' at the end, this will be done
# automatically to create a 32-bit value in your source code.
# Typical values are:

# F_CPU = 1843200

# This will define a symbol, F_CLOCK, in all source code files equal to the

# clock generation for the USB and other AVR subsections. Do NOT tack on a 'UL'
# at the end, this will be done automatically to create a 32-bit value in your
