Hi Juerg, can you explain why this is now invalid? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1982627 Title: MT7612u wireless chipset not working on Raspberry Pi 400 Status in linux-firmware package in Ubuntu: Invalid Status in linux-raspi package in Ubuntu: Invalid Bug description: I purchased the Alfa AWUS036ACM wireless adapter to use with my Raspberry Pi 400. The adapter works when using Raspberry Pi OS, but not when using "Ubuntu for Raspberry Pi" release 22.04. I have tested 64-bit variants for Ubuntu Desktop and Ubuntu Server, and the results are the same. I followed the Kernel Firmware Debugging steps, and included its output below. The LinuxWireless Debugging steps seem to only be appropriate if the wireless adapter is working to some capacity so the below output does not include those steps.

As part of troubleshooting, I updated the bootloader for the Raspberry Pi 400 to version 507b2360 which was built on 2022-04-26. I also ran `sudo apt update` and `sudo apt full-upgrade`. Neither of these troubleshooting steps resolved the problem. On a separate note, I have another Ubuntu Server release 22.04 that is installed on dedicated hardware (not the "Ubuntu for Raspberry Pi" variant), and the wireless adapter does work on this machine.

[Kernel-packages] [Bug 1982627] Re: MT7612u wireless chipset not working on Raspberry Pi 400
Looks like this is one of the ones moved to the modules-extra package (this split is kernel specific, and wasn't done on the PC kernel which probably explains why this adapter works on your PC installation of Ubuntu Server). If you do the following: $ sudo apt install linux-modules-extra-raspi You should then be able to modprobe usbmon. I'll move the bug over to linux-raspi as it's technically a kernel issue. ** Also affects: linux-raspi (Ubuntu) Importance: Undecided Status: New ** Changed in: linux-firmware (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1982627 Title: MT7612u wireless chipset not working on Raspberry Pi 400 Status in linux-firmware package in Ubuntu: Invalid Status in linux-raspi package in Ubuntu: New Bug description: I purchased the Alfa AWUS036ACM wireless adapter to use with my Raspberry Pi 400.

I also attempted to follow the Kernel USB Debugging steps, but the commands do not seem appropriate for the Raspberry Pi 400. For example, `/proc/bus/usb` and `/sys/kernel/debug/usb/usbmon/` do not exist on the filesystem. As part of troubleshooting, I updated the bootloader for the Raspberry Pi 400 to version 507b2360 which was built on 2022-04-26. I also ran `sudo apt update` and `sudo apt full-upgrade`. Neither of these troubleshooting steps resolved the problem. On a separate note, I have another Ubuntu Server release 22.04 that is installed on dedicated hardware (not the "Ubuntu for Raspberry Pi" variant), and the wireless adapter does work on this machine.
