pwpiwi 929b61c670 Always enable fast response mode (was enabled for flasher only) 
* ensure that CMD_ACK is used exclusively for the very last response of each PM3 operation. All Dbprintf() must be before.
* always switch off field before exiting
* append null packet for USB transfers % 64 bytes
* reformatting and whitespace fixes
