No USB detected on Raspberry Pi 4 with aarch64

[robg]

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:
$this->bbcode_second_pass_code('', '# pacman -S alsa-utils mpg123
...
% mpg123 02-The_Need_to_Dance.mp3

$this->bbcode_second_pass_code('', '% 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.
$this->bbcode_second_pass_code('', '% 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:

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.

I am encountering this issue now, but the method in the link mentioned above doesn't work, and going through the replies in this thread I can't figure out what I need to do. My biggest problem is that it seems the PI doesn't have any network connectivity, so I can't even SSH into it, making it impossible for me to do anything.

Try setting "total_mem=4096" (or anything below 4GB, e.g., 2048) in /boot/config.txt. This should allow you to boot with working USB peripherals (and internet?) The ALARM aarch64 image is meant to be installed on a RPI 4 with 4GB of RAM and apparently does not take too kindly to the 8GB version. If the above trick allows you to boot with a working keyboard, you can then install the linux-raspberrypi4 kernel which supports the 8GB RPI.
