USB 3.0 WiFi RTL8812AU module can't mounted usb3.0

Hello

I want to test Realtek USB 3.0 WiFi RTL8812AU module.

About RTL8812AU module reference https://wikidevi.com/wiki/CC%26C_WL-8210-V1

I compiled driver 8812au.ko to system.
But it verify mounted device on usb2.0,not mounted usb3.0.

ubuntu@tegra-ubuntu:~$ lsusb -t

Is there maybe other idea that enable usb3.0 ?
Thank you.

There are cases where it appears USB3 is enabled to the wrong root HUB, but “isn’t really”. The gist is that sometimes USB3 is enabled but appears as USB2 under lsusb tree view. Here’s a thread which discusses this around kinect v2:

First comment is that normally USB3 will not change performance at all on wifi adapters…they just don’t generate enough traffic to saturate USB2. This would possibly change in the case of other devices consuming HUB bandwidth. HID devices won’t be significant in bandwidth.

Second, I see the advertisement here is worded a bit vaguely about USB3 speed:
[url]http://www.ccandc.com.tw/products_2.php?prod=180[/url]
…by “vaguely” I mean that the advertisement suggests the adapter works on USB3, but never explicitly states it works at USB3 speeds. The device won’t fail on a newer USB3, but this does not mean USB3 is an advantage over USB2 for this particular device. The chipset says it is USB3 capable, but perhaps the adapter is only wired for USB2.

Here’s an image I found on images.google.com for USB2 versus USB3:

When comparing to USB3 images, does your wifi appear to have the version 3 connector? Without this USB3 cannot be achieved even if the chipset is USB3 capable.

thank you for your reply and the information.
Use usb2.0 enough, I think it may be possible to achieve this usb3.0 speed network environment in strict.
I will try in windows, make sure chipset USB3 capable.
Thank you linuxdev
