Hello,

I have tested various USB devices and all worked except the TL-WN823N.
This device has never worked and we have 2 of them.

On Ubuntu boot I get:
[ 1208.638541] usb 1-1: RTL8192EU rev B (SMIC) 2T2R, TX queues 3,
WiFi=1, BT=0, GPS=0, HI PA=0

[ 1209.735452] usbcore: registered new interface driver rtl8xxxu

When I attempt to connect at a 2,4GHz WPA3 SSID this is what I get:
[ 1502.319954] wlxd46e0eeba0f4: authenticate with c6:27:28:**:**:**

To make things worse, I accidentally inserted it in a USB 1.1 port on
my AMD test PC and it could not even connect to a combo 2,4GHz WPA2,3

On USB 2.0 port the problem with WPA2,3 SSID was resolved. Is it
possible to set a flag so that the driver will bail out if the device
is on a USB 1.1 port? The truth is that the maximum speed it reached
was way below the 12Mb of USB 1.1 so it should not have a problem but
in practise it does...

 This is the device:
