My USB Keyboard disconnects and stops working after some time.
The only solution is rebooting.
Unplugging and replugging doesn't work.
Changing do Keyboard doesn't work.
On Windows, it disconnects and reconnects after about one second.
On Arch, I'm forced to reboot.
I got the following message on /var/log/Xorg.0.log

I've searched several posts, but none could resolve my problem.
I add "usbcore.autosuspend=-1" to my /boot/loader/entries/arch.conf and it resolved the problem.
Thank you @seth

USB powersaving? https://wiki.archlinux.org/index.php/Po … utosuspend
Do the keyboard LEDs light up when you re-plug it?
"usbcore.autosuspend=-1" will disable autosuspending, but can and usually is overridden by userspace powermanagement daemons (TLP, laptopmode tools, …) at runtime, so be weary of that and consult the documentation of any tool you use on how to disable it there.
