Public bug reported:
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. 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.

MT7612u wireless chipset not working on Raspberry Pi 400

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. 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"
