That's good news! You may want to take a close look at the connector to see if that got stretched a little and simply wasn't making enough contact. Or by moving it around port to port you have dislodged some debris(dust, dirt) that got in there.

It sounds like Windows finally got around to detecting it properly. At least you now know it wasn't anything serious like a hardware fault or ?
