What do the LEDs mean?

Hi,

I am new to VESC and using a FSESC 4.20.

I cannot connect to it via USB anymore. (It worked until a bit ago.)

The LEDs show:
- Blue: Permanently On
- Green: Off for 1 second, On for 1 second.
- Red: On whenever Green is on

Is this a special (intended) mode, or did I break something?

Are the LEDs trying to tell me something? (Also, where would I look this up?)

Thank you,

Chaim Lukas
