USB hub not working (no keyboard/mouse)

Updated my iMac 9,1 to Sonoma without any problems (from El Capitan to Monterey to Sonoma). Unfortunately, I can't seem to figure out how to get the keyboard or mouse running again, even with a working USB 2 hub (although it works when hitting the option button to get to the boot manager). So, currently I am stuck on the login screen, because I can't enter my password. Is there a solution, did I miss something?
