I had a cable like this, it was for an ancient Medion digital camera. No idea why they went with the full size USB female socket on the device, but it was just a simple USB cable that had male plugs on each end. Maybe it was cheaper, maybe it had debug purposes… we will never know.

I also tried to connect two PCs with it, it was my very first thought when I saw that cable. Obviously, it didn’t work, nothing happened. Remember Total Commander had a “Connect two computers with USB” feature, was thinking maybe that will work with it, but nope… for that, a specialized USB cable/device was needed, not the one I had for the camera.
