I have a USB hub that works great with my CCwGT, but when replaced my OEM AC adapter with the OEM ethernet adapter, the USB hub doesn't allow the CC to see the ethernet adapter.
Do we know if any USB hubs are known to work with the Google ethernet power adapter?
Just plug a USB ethernet adapter into your hub and skip the Google ethernet plug?
I'd imagine that they subverted the USB standards and used some extra pins for the ethernet port or they have it showing up as a special device type, but if it requires the Chromecast to be acting in host OTG mode I haven't run across any hubs that can fake that.
