    Recovery after Download error

    Hi,
    I foolishly pulled the power halfway through an upload to a Teensy 3.5 board and now the board is no longer recognised as a USB / COM port on the PC and i can't upload to it.

    The board was powered by secondary source and the USB cable had the 5v disconnected. I've been using a setup like this for months with no issues.

    I've tried pressing, pressing and holding the reset button and nothing. I've also tried using a standard USB cable directly into the board and no com port comes up on the PC.

    Have i corrupted something and is there a way to recover this ?

    Cheers
