Guest bxs Posted November 18, 2021 Posted November 18, 2021 I note that to the left of the three ports for the J2i cage, there's a USB port. Is this for Apple diagnostics or can be used for other things? Has any one tried using it, and if so what did you plug in; a thumb drive, or something else ? Is it USB 3.1 or 3.2 or what ? Thanks... ? See attached image.... Source: MacRumors
