[Bug 2140502] Re: USB input devices (mouse/touchpad) stop working after upgrading to kernel 6.17.0-14-generic

Hi good day,

just want to say tanx alot to the hole Ubuntu team,

running Mint thou, but yeah it's Ubuntu.

I ditched Windows for good recently.

Running kernel 6.14.37 generic, all worx %.

After I updated to 6.17 my laptop won't boot at all, I had to enter the
grub menu and reload 6.14.37 again.

I see on some youtube vids, poeple already install 6.18 LTS.

It does not show on my Update manager.

God bless

Title:
USB input devices (mouse/touchpad) stop working after upgrading to
kernel 6.17.0-14-generic

Status in linux package in Ubuntu:
New

Bug description:
After upgrading to kernel 6.17.0-14-generic, USB input devices stop working immediately after boot.
The system becomes effectively unusable without reverting to an older kernel.

This regression did not occur with previous kernels (e.g. 6.14.x).

Steps:

> Install Linux Mint 22.2 (based on Ubuntu 24.04)

> Upgrade system packages, including kernel 6.17.0-14-generic

> Reboot into the new kernel

USB input devices (mouse / touchpad) should work normally after boot.

USB mouse stops working completely

Touchpad is also non-functional

Keyboard may work inconsistently or only partially

System cannot be used normally

Downgrading to an older kernel restores full functionality

Workaround

Booting into an older kernel via GRUB (e.g. 6.14.x-generic) restores USB input functionality.
Removing kernel 6.17.0-14-generic also resolves the issue.

System Information
OS: Linux Mint 22.2 x86_64
Base: Ubuntu 24.04
Kernel: 6.17.0-14-generic
Host: Acer Nitro AN515-43
CPU: AMD Ryzen 5 3550H (Raven Ridge)
GPU 1: AMD Radeon Vega Mobile
GPU 2: NVIDIA GeForce GTX 1650 Mobile (Max-Q)
DE: Cinnamon 6.4.8
Architecture: x86_64

This appears to be a kernel regression affecting USB / HID input

The issue happens immediately after boot, before any user interaction

The same hardware works correctly with older kernels

No custom kernel parameters are in use
