So it's definitely not related to your kernel. I will try to find some time next week to see what settings pulseaudio-alsa imports and that (may) need be added to the kernel. Since this is now diverging from the original (USB) topic, I'll open a new thread when I get around to investigating.

Many thanks again!

Seems one solution is to add dtparam=audio=on to /boot/config.txt. After doing that, as long as your user is in the audio group, it works as expected:
Code: Select all
# pacman -S alsa-utils mpg123
...
% mpg123 02-The_Need_to_Dance.mp3
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layers 1, 2 and 3
   version 1.26.3; written and copyright by Michael Hipp and others
   free software (LGPL) without any warranty but with best wishes


Terminal control enabled, press 'h' for listing of keys and functions.

Playing MPEG stream 1 of 1: 02-The_Need_to_Dance.mp3 ...

MPEG 1.0 L III cbr128 44100 j-s

Title:   The Need to Dance                                       Artist: The Jerky Boys                                         
Comment:                                                         Album:  The Jerky Boys 4                                       
Year:    1997                                                    Genre:  Unknown                               


Code: Select all
% id
uid=1004(facade) gid=985(users) groups=985(users),995(audio)


This is under my kernel/aarch64 (5.10.y) or the current repo kernel (5.4.83).

And it only works without the kms driver. With the kms driver it does not work.
Code: Select all
% cat /boot/config.txt
# dtoverlay=vc4-kms-v3d
dtparam=audio=on
hdmi_force_hotplug=1
over_voltage=6
arm_freq=2000


Yet booting with it:
Code: Select all
% mpg123 02-The_Need_to_Dance.mp3
High Performance MPEG 1.0/2.0/2.5 Audio Player for Layers 1, 2 and 3
   version 1.26.3; written and copyright by Michael Hipp and others

Hi, I might be a bit late but I've found a post that goes over the solution for this issue. Here's the link :

https://kiljan.org/2021/02/20/64-bit-arch-linux-arm-on-a-raspberry-pi-4-model-b-with-8-gb-of-ram/

I followed the instructions on the link and my USB ports are working fine now.

Thank you, the author uses the upstream kernel linux-raspberrypi4.
Btw the post is quite recent, Feb 2021.
