USB flash drive is different from the current version used by the power supply. As long as the firmware
version on the USB flash drive is different from that of the power supply, the firmware update (or reversion
if a previous version exists on the USB flash drive) will occur.
The LCD GUI image file naming format will be imNN_XXX.hex, with NN being the image number (0-5)

used by the power supply. As long as the LCD GUI version of the USB drive is different from that of the
power supply, the image update (or reversion) will occur.
