BananaPI OpenWrt 22 and USB WLAn Stick rtl8812au-ac

Hello everyone,
i need your help.
I am trying to set up an access point with my old BananaPI using a USB Wlan Stick AC1900 (rtl8812au-ac)
After installing the kernel module, the stick is also recognized, but the interface cannot be loaded.
Unfortunately I have no idea why OpenWRT doesn't do this?
Can it be that the driver rtl8812au-ac has an error?
Maybe one of you can help me.
Thanks very much
LG

Because Realtek suck, especially if you want AP mode.

Is there a list in the wiki about which wifi add-ons (USB and M.2) work and which suck? I couldn't find one just now, but I recall seeing something like that somewhere ("don't get an Intel AX200 if you want to use it as an AP" sort of thing).

There's https://github.com/morrownr/USB-WiFi/ for USB adapters.
