No communication over USB[ New ]
I was able to use my GoPro HERO9 as an MTP device without issue, then it just stopped working. I've tried resetting the camera to factory settings but there is still basically no communication over USB.
I have a suspicion that connecting to a GMC vehicle USB port to charge while recording put it in a bad state at the USB level that it can not get out of. Is there anything I can try to remedy this? It does charge, but there is no data activity.
I took a trace of USB bus activity using Total Phase software that someone at GoPro could look at if thats helpful.
