I've tested the hub and PD power adapter (Anker) on the same laptop on the
Windows 10 partition. No luck. The PD chip in the laptop is recognised by
Windows 10 though.

I've ordered a replacement adapter (Anker), and hub, which should arrive
tomorrow - I'll see how that goes.

At this point, its either one of three things:

- The laptop hardware.
- The USB-C hub.
- The Anker power adapter.

Time will tell....
