No inputs possible on login screen

Hello Board

Yesterday my eos crashed during a system update and deleted systemd-boot (again). I fixed that. Now however, when i get to the lightdm login screen, i can’t move my cursor or type anything. Also when i plugin another keyboard or mouse it still wont work. However, i have luks full disk encryption enabled and here i can enter my password when the kernel is about to mount my ssd.

Also the login screen is not frozen, since it changes to the idle state after a minute (or so).
I tried to reinstall every package on my pc and reinstalled the kernel several times but still no success.

It seems that the USB hub driver does not work? Is that even possible? This is on my laptop, so i do not have any other (PS2) ports. Thunderbold also doesn’t work any more.

Any suggestions? Thanks!

Regards,
Kris
