The one on the right side? I've lost my USB cable for my Samsung R10 and trying to buy a new one but for the life of me cannot get the name of it! It's described as a "combo AV-out, Component-out, USB port" in the manual. Yes I'm probably being stupid and it's obvious but cannot seek the answer tonight it seems Thanks!
Custom port if it's a combo analogue + digital port it'll need a custom cable, so search ebay or parts people
