It's not actually a privilege issue, that's just the general "couldn't
open device" error (which historically with serial ports used to be
about permissions).

Do you get any debug messages when you run subsurface from the command
line? Can you cut-and-paste those into the email?

It *should* say something like the appended (plus a whole lot of
service discovery and then data transfer noise), while the G2 screen
says "connected".
