Default [Q] USB Port Issue?

Well, I'm stumped.

Plugged in my G2 to my car charger yesterday and noticed the cable itself and both connectors getting quite hot. Tried different chargers, cables, etc and same thing. Further troubleshooting today and I was able to get it to see a computer once, but now, with cable jiggling, etc, best I can do is get it to see USB charge on computer, no adb/data, etc. No issues with wireless charging at all.

VZW, Running CM-M4. I had always had some issues getting the phone to recognize charging/not charging before, but always was a software thing. (Take off charger, phone still thinks it's charging for awhile, etc).

I'm confused. I very rarely use the USB port, maybe 3x a week since always use wireless charging so seemed odd to already have a H/W issue with the USB port.

Thoughts?
