It's the controllers micro USB port. I sprayed some electrical component cleaner in it, plugged it in and unplugged it multiple times (to get the cleaner to penetrate and clean the contacts) then wiggled the cord end at the port a few times, started working again. I've even unplugged and plugged it back multiple times, works like a dream. Hope this helps someone else!
