[Moto X Q&A] andresrivas:
Hello!

My phone is nearly 2 years old.. Works fine and I am very happy with it. Well, was. Turns out that a couple of months ago suddenly the usb port started to act very strange:

When I connect to a pc, the device identifies it as a charger, and (in linux) got this on the pc's console:

And, of course, I got zero conectivity and the phone does not charge the battery.

If I plug in the charger, then it charges, but VERY slowly (like usb data connection slow) and it doesn't recognize the charger (no "charging..." status on battery).

I checked the usb connector and it's fine, no signs of desoldered, fasle contacts nor water damage (althrough it got soaked once, was like 6 monts ago and usb was still working correctly)

I'm baffled, can't think a logic explanation for this behaviour...
