Incredible, thank you for the fast response, Dave! Installing the linux- modules-extra-raspi package did indeed allow me to modprobe usbmon, and the Wireless AP to be recognized by `iw list`.

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. 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. #### Raspberry Pi 400 Output #### $ sudo modprobe usbmon modprobe: FATAL: Module usbmon not found in directory /lib/modules/5.15.0-1012-raspi $ lsb_release -rd Description: Ubuntu 22.04 LTS Release: 22.04 $ apt-cache policy linux-firmware linux-firmware: Installed: 20220329.git681281e4-0ubuntu3.2 Candidate: 20220329.git681281e4-0ubuntu3.2 Version table: *** 20220329.git681281e4-0ubuntu3.2 500 500 http://ports.ubuntu.com/ubuntu-ports jammy-updates/main arm64 Packages 100 /var/lib/dpkg/status 20220329.git681281e4-0ubuntu1 500 500 http://ports.ubuntu.com/ubuntu-ports jammy/main arm64 Packages $ sudo udevadm control --log-priority debug $ tail -f /var/log/syslog Jul 22 20:56:03 ubuntu kernel: [ 533.687623] usb 2-1: new SuperSpeed USB device number 3 using xhci_hcd Jul 22 20:56:03 ubuntu kernel: [ 533.709177] usb 2-1: New USB device found, idVendor=0e8d, idProduct=7612, bcdDevice= 1.00 Jul 22 20:56:03 ubuntu kernel: [ 533.709203] usb 2-1: New USB device strings: Mfr=2, Product=3, SerialNumber=4 Jul 22 20:56:03 ubuntu kernel: [ 533.709214] usb 2-1: Product: Wireless Jul 22 20:56:03 ubuntu kernel: [ 533.709222] usb 2-1: Manufacturer: MediaTek Inc.
