Ah, thank you. I’ll have a go at that then.

Are you referring to the #define MASTER_LEFT?

This is just defining whether the USB is plugged into the left board or right board.

All defines start with a hash as standard. It’s not commenting the line out. For that, you’d use //.

I’m an avid Void user, so I get the value of linux. But I cringe every time I see a comment like this. The OP has asked a specific question about a specific version of a specific OS. Someone asking about an OS should not be considered an invitation to tell them about another.
