I have an in-line USB power meter that is super handy to see if something is drawing power and how much.

EDIT: Here's the manual as PDF. Jump to the Charging the Reader section.
I think you might be on the money with the pc usb charge comment.

Looking in the section on charging in the manual I noticed it mention that you should have it switched on, not just in sleep mode, before connecting the usb cable. I had not been doing that.

I tried both with the pc (laptop) and the red light came on after a few seconds. I then tried with the non pc ports and no usb charge light.

So leaving it on the laptop charge now. Let's see what happens...
