USB 3.0 support?

Is there any way to make the rtl8812bu usb3.0 stick really use usb 3.0?

I believe it is not related to driver. This device utilizes usb 2.0 speed. My Spacetronik AC-1200 looks like usb 3 because of blue connector but it is really usb 2.0.

I would like to bump this issue. I am working towards around 100 of cards using this driver, and they seem to be dropping and picking back up in much the same way listed. It appears they are also only running at USB2 speeds.
