Lakka pc installer doesn't recognize usb keyboard

I am having a tough time with lakka pc. I am trying to run the installer but the installer is not recognizing my USB keyboard or the ps4 controller plugged in so I’m unable to select options and run the installer. I’m using an amd64 processor and a gigabyte motherboard. I’ve tried enabling USB keyboard support and I’ve also tried enabling iommu (had to enable it for my USB keyboard to work for Ubuntu). I don’t have a ps/2 keyboard to use instead. Help on what I should do would be greatly appreciated
