The USB Keyboard and mouse are not operational once I get to the XUBUNTU login screen. They work during the bios setup. I am on XUbuntu 16.10. I can dual boot to windows 10, ok, it seems. I have the latest BIOS 3101. I have tried disabling fast boot, no change; enabling xHCI and/or EHCI, no change, full and partial USB, all with no change... I was able to take a picture of the boot error messages and it is attached. Please, please help, I am quite desperate...
