fusb302 4-0022: connection has disconnected

acidpero

There is no problem to using board
However, I wanna know why the 'USB Type-C' is on the board and why the error like the title occurs.
I wonder why this is happening.
please let me know.

Hi, @acidpero, how did you get that message?
After booting up, I only get this:

Hi again, @penguin
I got Firefly:Ubuntu 16.04 image
[Here!](https://drive.google.com/drive/f ... gAqAdXBsaG9NMEl5bm8)
and flashed the image with the upgrade tool.

------------------------------------

when boot without connecting the USB Type-C port to the Host PC, I got the same message like yours.
But when I boot them with both connected, I got the following message.

I would like to know why there is a USB Type-C port other than flashing.
