Hello,
The problem lies in changing the camera software or electronics design.
I have a camera purchased from 2016 (version 1.00.15), and a new camera bought a month ago (soft 1.00.28).
In the older version, after connecting the USB port (camera port) a menu appears with options: Mass storage / PC camera / Camcorder.
This is not the case in the new camera, I also noticed that it can work independently, without a base battery (the older one immediately loses the memory of the date and time), probably this port in the side wall is used to charge the internal battery.
For me personally, this is a stupid change, because it forces you to have an adapter / card reader and insert / remove the card, but
difficult.
I received a response from the seller - changing the software of the camera forced Windows10, problems with detecting the camera, interrupting
when ripping movies and long copying time. Apparently, this is not the first producer who stopped supporting computer communication.
Greetings,
Paul.
