[SOLVED] USB disconnects

I installed Arch a few days ago, dual-booting with Ubuntu 24.04 LTS (6.8 kernel).  Previously I've been using Ubuntu exclusively on this PC for about 5 years.

My keyboard and mouse keep disconnecting every 2-3 minutes in Arch.  I have to unplug them and plug them back in to work, but that only buys me a couple more minutes.  Note that this issue *does not happen at all* in Ubuntu.  I tried a Manjaro live USB and the problem also happens there.

The kernel I am currently on is Linux 6.12.13-1-lts #1 SMP PREEMPT_DYNAMIC Sat, 08 Feb 2025 15:16:04 +0000 x86_64 GNU/Linux

I also tried the non-lts, same issue

Stuff I have tried:
Added this file:

/etc/udev/rules.d/99-no-usb-powersave.rules:
ACTION=="add", SUBSYSTEM=="input", TEST=="power/control", ATTR{power/control}="on"

Added this to /etc/default/grub (and ran the grub-mkconfig)
GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 quiet usbcore.autosuspend=-1"

Installed "linux-lts" (booted into it and ran `uname -a` to make sure I landed on the right one).

The issue is evident in dmesg:

what else can I try?  I heard Arch was really stable but my experience has been anything but

Re: [SOLVED] USB disconnects

This issue looks similar and suggests that the bug is in 6.12.8 and later https://community.frame.work/t/audio-ex … able/62951

Re: [SOLVED] USB disconnects

Same thing happens to me, USB keyboard keeps reconnecting all the time after computer is powered on for a while. It started happening to me like 1 or 2 weeks back.

kernel: usb 9-1.2: reset full-speed USB device number 4 using xhci_hcd
kernel: usb 9-1.2: reset full-speed USB device number 4 using xhci_hcd

Edit:
After actually checking your log messages I think its different issue that seems similar on the first look.

Re: [SOLVED] USB disconnects

I was able to workaround the issue by installing linux-lts66 via AUR. I'd like to report the issue upstream so I can eventually use newer kernel, but not sure where to do that. For now, I go back to ubuntu to use newer kernels

Re: [SOLVED] USB disconnects

Is the issue also present in the latest kernel release candidate?

sudo pacman -U https://pkgbuild.com//\~gromit/linux-bisection-kernels/linux-mainline-6.14rc3-1-x86_64.pkg.tar.zst

This way we don't start investigating a bug in detail which may already be fixed in a newer version ..

(note that this installs the kernel as linux-mainline, so you need to configure your bootloader to boot it (for example via grub-mkconfig -o ... or by writing the systemd-boot loader entry))

I tried `linux-git` package yesterday and the bug was present there.  I will try this one later today when I have a chance, but I suspect it has the issue.

Re: [SOLVED] USB disconnects

if I had to guess, I would guess that this change is responsible given the nature of the change: https://github.com/torvalds/linux/commi … 32c7a8da4e

I will try to reverse patch the source later if I can make time for it to test

Re: [SOLVED] USB disconnects

unfortunately my C is not good enough to work out a patch, hopefully someone can direct me how to contact the package maintainer, because this bug is present in all versions of Linux (and all distros) with kernel 6.9+

Re: [SOLVED] USB disconnects

upgraded ubuntu to kernel 6.11 and it also presents this issue. so it is not an arch specific problem

Re: [SOLVED] USB disconnects

I updated my UEFI from 1.10 to 2.10 (ASRock Z590 Steel Legend) and the problem appears to be resolved for all kernel versions.  I need to use it a bit longer before I'm sure but it's unusual for it to be healthy for this long (~20 min) in kernels 6.9+

I don't know why new kernels don't like the old UEFI version, but posting here in case others have this problem.

Many thanks to everyone above and on the arch discord for helping me to troubleshoot this issue.
