Do I have to adjust any settings to get an external USB mouse working?
The trackpad on the laptop works fine.

I have tried under Wayland using sway and labwc. The mouse LED lights up
but the pointer won't move and the buttons don't cause any
actions. I tried two mice and they work on my desktop. I also tried
different USB ports.

My setup:
Laptop: Acer A315-21

Linux 6.6.42-0-lts #1-Alpine SMP PREEMPT_DYNAMIC 2024-07-25 10:49:31 x86_64 Linux

wayland-1.22.0-r4

sway version 1.9

labwc 0.7.2

Dmesg of mice:
