MBP Late 2016 Thunderbolt 3 issue: connected cables not recognized after sleep/wake up
I've had a similar issue with the Monoprice Select Series USB-C to 3x USB-A 3.0, Gigabit Ethernet &amp; USB-C Adapter. If I use the MacBook Pro 2016 w/ touchbar in clamshell mode with this adapter, the MBP will not wake from sleep at all. It's almost as if the adapter has gone to sleep, even though the lights on the ethernet port light up and blink and the AC adapter is plugged into the usb-c port on the adapter.

I have another ethernet adapter made by Anker that has 3 USB-A 3.0 ports on it that works just fine though. Might be a difference in chip set?
