## USB devices not detect before "$ adb devices"
I connect VOXL to my Ubuntu20.04 laptop but "05c6:901d" and "18d1:d00d" don't show up but just "0403:6001" when I do "lsusb" command.

I tried several USB cables and another PC but I always get same output.

==P.S.==
I'm using "VOXL CAM + TOF Dev Kit w/ Flight Controller".
The green LED turn on and not blinking.

It looks like you might be inside of the docker, can you try from command line?

@Moderator 

I didn't use docker. 
(certainly, the screenshot folder looks like inside docker)

This problem was solved in another way
I made a mistake in the port to insert the micro USB.
