PS4 USB won't charge controllers.

I came in from work yesterday after plugging in my controller to USB in the morning and found it uncharged. I usually play in morning, plug up controller and play in the evening. I tried the other port, and my other controller to no avail. The controllers charge on the charging dock or via USB on other devices. My PS4 is a launch version just over 3 years old.

Anybody else experienced this?

Thanks in advance.
