Ubuntu Server 20.4 not detecting ZEB-USB150WF1 driver

Hi @alan_g, @ogra
I am using Zerbronics ZEB-USB150WF1 for external wifi adapter in Raspberry pi 3B+ with Ubuntu server but I am not seeing the adapter for that. What could be the reason?

USB adapter is detected by the OS :

Bus 001 Device 004: ID 0461:0010 Primax Electronics, Ltd HP PR1101U / Primax PMX-KPR1101U Keyboard
Bus 001 Device 005: ID 0bda:f179 Realtek Semiconductor Corp.

but adapter is not showing

It should show wlan1 for external adqapter.

please file a bug against the kernel with:

ubuntu-bug linux-raspi

(i’m not sure if the driver for this card is freely distributable as part of the linux kernel or if you need some externally built dkms kernel module (because the card is too new or because there are legal issues), the kernel team will know though)

Can you guide me to do that, because I do not know how to do that.
