* - The makefile EEPROM programming targets for FLIP and dfu-programmer no longer program in the FLASH data in addition to the
* EEPROM data into the device. If both are to be programmed, both the EEPROM and FLASH programming targets must be called.
* - As the avr-libc macro has been corrected in recent avr-libc distributions, the SetSystemClockPrescaler() macro has been removed.
* Include <avr/power.h> and call clock_prescale_set(clock_div_1); instead on recent avr-libc distributions.

* - The USBtoSerial demo now discards all data when not connected to a host, rather than buffering it for later transmission.
