Hi @dgatwood, @jazzzz, I think we should try a test kernel with the VIA chipset changes reverted, to see if it is the commit causing you issues.
I have a couple of test kernels based on 5.11.0-44-generic for Focal HWE and Hirsute, and 5.13.0-23-generic for Impish currently building, and they have the below commit reverted: commit 5caa90d5fedfcdf57a42c272896cfd0ef6b5c667 commit-upstream: 5255660b208aebfdb71d574f3952cf48392f4306 Author: Jonathan Bell <jonat...@raspberrypi.org> Date: Fri Oct 8 12:25:44 2021 +0300 Subject: xhci: add quirk for host controllers that don't update endpoint DCS Link: https://github.com/torvalds/linux/commit/5255660b208aebfdb71d574f3952cf48392f4306 Its building in https://launchpad.net/~mruffell/+archive/ubuntu/lp1956849-test and will be ready in a few hours, although I will post proper instructions on how to install the test kernel tomorrow. I will write back once the kernels have finished building, and I have had a chance to boot test them.

It disables almost all USB-3.0 and USB-C ports completely. Even though I had automatic software updates turned OFF (or so I thought), my Mac Pro suddenly got a new kernel when I rebooted it this morning: Linux macpro-obs 5.11.0-44-generic #48~20.04.2-Ubuntu SMP Tue Dec 14 15:36:44 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux and it contains a P0 showstopper bug. Upon rebooting, I got dropped into the initrd prompt because Linux could not see the external USB drive that I'm booting from (WDBAGF5000AGY-WESN). I wasted an entire day figuring out what was wrong, and even went so far as to order a replacement SSD, planning to rebuild everything from scratch, because the drive failed to appear in every single USB port I tried. Then I discovered that a different SSD didn't work, either. At that point, I realized that something else was wrong, and I kept trying until I found one other port that worked. I was then able to boot and get dmesg and lsusb output. This kernel update broke not only the built-in ports, but also the ports on a generic USB-C PCIe card (Amazon B08PF8XR73). Mac Pro built-in USB-3.0(A) ports (2x): working Mac Pro built-in USB-C ports (4x): dead USB-C PCIe card USB-C ports (2x): dead USB-C PCIe card USB-3.0(A) ports (5x): dead All devices fail to appear in lsusb when attached to the port, including an Apple USB keyboard, an Anker USB-C Ethernet adapter, a WD SSD, and a Sandisk SSD. I'm going to roll back my kernel to a working kernel, but this package needs to be pulled NOW before it affects too many people. This is too catastrophic a bug to wait even a day.
