Flashing tool from usb-flasher/ directory can be used to flash the
firmware over USB.
For example to build and flash your own firmware you could run these
commands:
# save the original firmware in case you want to restore it
./usb-flasher/ppkb-flasher info > saved-info.txt
./usb-flasher/ppkb-flasher --rom-out saved-rom.bin read
# build the new firmware (you may need sdcc 4.1, older versions may
# miscompile the firmware)
(cd firmware && ./build.sh)
# flash the new firmware
./usb-flasher/ppkb-flasher --rom-in firmware/build/fw.bin write reset
