After kernel update unfortunally my pc don't recognize usb keyboard

I've a dm-crypt lvm setup and a boot partition sda1 - so far to the setup -

After a normal pacman -Suy I got this problem that the usb keyboard isn't recognized anymore -

A fallback image works fine by the way thats why I pointed the problem to the kernel in my guess,

but maybe something else is wrong mkinitcpio.conf seems to be correct HOOK="keyboard keybmap before filesystem etc."

Do you have an idea, I'm clueless...

- would it help to downgrade to the Kernel before and see whats happen, if it's working again?

If you still have the other kernel before the upgrade in your grub menu roll back to that kernel.

If you know what module the kernel is using to communicate with the keyboard (and if it's still loading) you can dmesg the driver and see what the output reveals. Other than that I don't know what else you could try. Drivers are in the output of lsmod.

Code:

dmesg | grep <name of driver>

Over time I had the same problem like you and had to purchase a new keyboard because mine was about 6 years old and Slackware didn't see it anymore after a kernel upgrade.
