Aufero Laser 1 disconnected

[LaserWillie (Willy)]

There’s an issue with Mac and Big Sur, you can search the forum for it but here’s one.

Can't connect to RUIDA 6442S via USB on Macbook Air M1 Mac Os X 11.4 (big Sur)

Probably, but I’m also sure you’re not the only one with the issue:) I understand USB-c is a different animal with more data paths. I didn’t think it was very standard now.
