RT1011 Nano Kit fails to enumerate

[elrom]

I'm getting the following issue with the RT1011 nano. (see linux dmesg below) Things I've tried:

1. Tried on windows
2. Tried on linux
3. a bunch of different cables
4. pressing reset twice to bring up uf2
5. I have two RT1011 nanos - tried them both

Despite all the above combinations, these don't seem to work. What do you suggest?

dmesg:

[113975.840229] usb usb7-port1: Cannot enable. Maybe the USB cable is bad?
[113976.727726] usb usb7-port1: Cannot enable. Maybe the USB cable is bad?

Update:
I can get it working if it's hooked up through a usb hub. Perhaps it's drawing too much power?
