Re: Ax88772b Linux Driver !!EXCLUSIVE!!
Laverne Levenstein
I just began to introduce myself to Risc OS, and after a few weeks I find it fascinating. I have been playing around with a Raspberry pi 4, however, I find out that Risc OS only use one core, and then came to my mind to use a Raspberry pi Zero. However, I can not make the pi Zero to recognize a USB Ethernet Adapter (Lenovo USB 2 Ethernet, based on the AX88772B chipset). I find this post Supporting the Pi Zero but it is not clear to me if in 5.28 there is anything to be done. I understand that new versions do not have the drivers to support other ethernet adapters that the one in the pi (and the Zero does not have one). So I was wondering if I missing something. Any guidance is welcomed!
And I did not work. But I then thought on checking the vendor and product id for my adapter. I used Raspberry pi OS and follow this guide to identify the vendor and product id for my adapter( -usb-devices-linux/), made the changes in EtherUSB, and voila! it worked!
Bluetooth works, but not wifi. I tried linuxmint 20.3 cinnamon (11, 13, and 15 kernels) and fedora 36 as well as the current ubuntu 22.04 LTS with 15.5 kernel and none of them detect the wifi card (all of the detect bluetooth from the card, but not wifi). tried installing iwlwifi drivers / firmware, including the backport.

The WLAN worked in Windows 11 with the previous card (realtek); I switched from windows to linux and the realtek was not detected. so, i purchased the ax210 m.2 card thinking it was a hardware failure. I have yet to see the ax210 card work for wifi (but I no longer have my windows key, so i cant reinstall).
Most HP BIOSes have a whitelist of allowed wifi cards, the AX210 isn't on it. Its pci device gets blocked effectively, only the USB portion of the device is usable. I'm staring at the AMITSE and Setup UEFI bios modules (where the whitelist seems to reside) for my own laptop (hp 15s, also ryzen) now in a hex editor.
