Could the firmware flashing instructions please be updated to note that the unit should not be powered externally when pressing and holding the button and connecting to the computer.
" Connect RaceCapture/Pro in Bootloader Mode
while holding down the front panel button connect RaceCapture/Pro to your computer using the USB cable.
You should observe the power LED, and the two rightmost green LEDs illuminated steady. You can now release the front panel button.
RaceCapture/Pro is now in bootloader mode "
Because if it's powered externally the two rightmost green LED's do not illuminate steady, external power to the unit must first be disconnected. Would be great if the firmware flashing update instructions could be updated accordingly.
