+ *  After running this bootloader for the first time on a new computer, you will need to supply the .INF
+ *  file located in this bootloader project's directory as the device's driver when running under Windows.
+ *  This will enable Windows to use its inbuilt CDC drivers, negating the need for custom drivers for the
+ *  device. Other Operating Systems should automatically use their own inbuilt CDC-ACM drivers.

+ *  On 64 bit versions of Windows, the OS requires all drivers to be digitally signed before it will allow
+ *  them to be installed. As Windows' own CDC driver (which the supplied INF file references) is not signed,
+ *  you will need to reboot, press F8 before Windows begins to load and select "Disable Driver Signature
+ *  Enforcement" to allow the CDC driver to install.
