Update from Sierra to High Sierra - No USB working at all

I have just updated to High Sierra according to the Update-How-To on Tonymacx86. The update went well, however I can't login as the USB ports don't seem to work at all. I have tried plugging in the keyboard into every USB port on my mainboard (Gigabyte Z170X-UD5-TH) without any improvements.

I read that my Clover KEXTs are probably missing a "usbinjectall.kext". I would like to add this but there is no way to interact with my Hackintosh as no USB port is working. How can I add KEXTs without being able to log into MacOS? The keyboard and mouse are working fine in BIOS and clover boot.
