hwinfo64 pic of enclosure ports (Aorus, XG Station 2, Razer Core)  

Not sure how one would use this screenshot to determine the USB 3.1 generation. Here it is:

@switch, thank you for the post. It looks like your USB 3.0 HDD is "[port4] Generic Superspeed USB Hub"-> "[Port3] USB mass storage device". If you connect your HDD to another Aorus USB 3.0 port does it appear under [port4] as port1, port2 or port4?

If I move it around the 3 USB ports, it appears as either Port 4 -> Port 1, Port 4-> Port 3 (this situation was pictured above) or Port 4 -> Port 4. I am assuming that Port 4 -> Port 2 is unavailable because the Port 2 under Port 2 is the QuickCharge 3.0 controller that's running the orange charging port on the Aorus (see the USB 1.1/2.0 controller under Port 2 -> Port 2).

Here's the pic without extra text (feel free to repost it):

@nando4 alright I got it. 
Aorus Gaming Box

Hope one of these shows what you need. I have keyboard mouse and headset plugged in to the box for it.

Here's the Razer Core.

How do you guys tell this is about USB 3.1 Gen 1 and not Gen 2?

@switch, you can see on the right pane:

• USB Device Version: 3.10 (or 3.0 in the case of the Razer Core)
• USB device speed: USB 3.0 SuperSpeed

Worth pointing out too all the enclosures are using Genesys Logic USB 3.1 or 3.0 hubs (VID 05E3), that have no  USB 3.1 Gen2 controller product on their website:

I see. Thanks for pointing that out. For my two cents... I don't mind the "low" bandwidth. I just mind Intel's implementation with "reserved" bandwidth. eGPU should be exempt from that silly regulation, as it doesn't need H2D DP. Most of the time, that is.

Here is mine – Aero 15 with HP Omen Accelerator attached.
