I bought this to use with my Oculus Rift and the info SAYS it should come with a power adapter for longer cables. Well I bought a 50ft cable but it did NOT come with a power adapter. I know that anything beyond a certain distance takes extra power to move data back and forth as it loses power over time. So I'm hoping the original seller sees this and asks me to send me a 5V 2A power adapter to plug in to finish setting up my VR setup for my kids.
