I just got this in the mail a few days ago. First few test runs were fine, figuring things out(I've had p1 and p2).
Ran into this issue today, everything connects just fine, but as soon as i go into the app for FPV it flashes on and off USB Connecting.
Searched the googles and didn't come up with much. Only thing I can think of is something being barely loose when I replaced the rubber pieces on the gimbal with new ones(I bought this 4 months used). possibly unhooked a wire? i didn't see anything that wasn't plugged up.
