Hmm never thought of doing that so I tried it out. Works fine for me using Skydios supplied USB-C cable to USB-C port on Surface Pro X and I tried a GoPro USB-C Cable to standard USB on my Desktop and it worked fine. Honestly I just use a card reader. I'm always cautious about plugging a drone into my computer directly, hate for me to bump it, catch cable or something and it hit the floor. Plus seems quicker copying by SD card reader.
Good to know. Skydio did not supply a "regular" USB cable (one that would fit into a desktop computer) so I was forced to use another USB-C cable that I have. Perhaps that cable is faulty. I tried another. Nope. Nothing.
Skydio responded to my support request by copying and pasting the original instructions, as if that would help.
I need someone to actually diagnose and fix the problem.
