The driver for USB is in the standard kernel. It just wasn't included in the initrd created during my installation, at least not the one for the USB keyboard, as I did the installation with another, old PS2 keyboard *and* chose "only necessary drivers", not "generic", which includes all the available drivers into the initrd, if I understand correctly. So, as no USB was being used during install the installer included no USB drivers in initrd, I think. In my case the problem didn't have anything to do with licensing or non-available non-free software or something like that.
