Can't access my keyboard or mousepad

Hello! I'm trying to install Mojave (10.14) on my laptop. I get it to boot, but I cannot controll the mouse. I am using the trackpad (I don't have acces to a mouse)

System:

Lenovo thinkpad T400
Core 2 Duo P8600
EFI legacy boot
6 GB RAM
Running the system from USB thumb drive
