I'm having the same issue with my 3D pro. Not getting much help anywhere either. I honestly think at this point its the motherboard. I've tried SEVERAL different USB cables with no luck. Response here is way to slow, if any, as well. For me it would speed things up to have the ability to go over USB vs Slicing, saving, ejecting, plugging card in, when I could just slice and then print. Still waiting to hear from Creality on possible board replacement. The board obviously wasn't tested before installing and shipping. Good luck!

RE: how to connect ender 3 v2 to PC?
SD card wiped
The SD card that came with my Ender 3D Pro somehow deleted all and now states it needs formatted. I'm unable to access the files and etc that came with my printer. I can't get my printer to be recognized to my PC over USB either. Is there a way I can redownload the software and etc that came on that SD card?
