Using a Kali Linux live USB with the latest version of Kali, 64 bit. I can boot into Kali, choose what want to do with my keyboard. I choose live(AMD64), it loads to the desktop but my mouse, razer naga and keyboard, razer blackwidow, are not being detected. as they are not working and are not lighting up. I used the exact same .iso file in a virtual machine and my mouse and keyboard worked fine. My main OS is windows 10, but i'm pretty sure this won't effect anything. Any help is appreciated and i will be sure to give extra info if anyone needs to know anything else.
Edit: Found out it was the back USB ports on my desktop. I have a gigabyte motherboard and have found that it was to do with iommu being disabled. When I enable iommu my live USB can boot into Kali boot options but when I click live(AMD64) it eventually returns "(initramfs) Unable to find a medium containing a live file system" when I turn iommu off again, it boots fine.
