Query: Useless junk

It's recogized as a USB joystick, and it supports button presses. The only part that doesn't work is the direction pad, it reports absolute garbage there. Without touching anything, the left button reports being constantly tapped. The down arrow does absolutely nothing.The unit I got is labeled Retro-Bit, not RetroLink. Maybe earlier buyers got something that works, but those glory days are long behind. If it were simply unable to make a USB connection, or not recognize a controller, then yeah, I'd figure it to be broken. I just can't imagine how the 5 lines of code that go in-between the two can go wrong, unless it was never implemented.
