First, check for a bad USB cable. Just swap it out and see.

Second, about the power draw: besides Dan’s question, you might consider getting a tester. Klein Tools makes a tester, about $40 I think for the better of the two models, that checks the available current from the port and the draw of the device, plus of course the voltage (5).
