Well, I was tearing apart a USB cable and an XBox dongle to make a USB XBox adapter to use dance mats/XBox controllers on my PC. Should've been moderately easy, since the USB and XBox wires ought be identically color-coded. For some reason, though, my USB cable's colors are out of wack and I don't know which is which. The USB, once the outside has been stripped, reveals red, white, brown, yellow and blue wires. There ought be red, white, black and green wires. (Sorry for the cruddy picture: Cheap digi cam + thin wires + shaky hands = bad picture) So, which wires are which? I'm guessing that the blue is the other data wire (should be green), and brown is the grounding wire (should be black). I'm hazarding another guess, that the yellow wire serves the same purpose as the yellow wire in the XBox cable. Again, not entirely sure. Help would be appreciated.
