keyboard and mouse not recognized on GA-Z170-HD3 DDR3

[friendoffriends]

Hi!
I bought all the parts of my first build following the Tonymacx86.com buyer's guide:
Gigabyte Mainboard GA-Z170-HD3 DDR3
16GB RAM
i5 6600
Cruical MX300 500GB
no graphics card yet

I prepared the USB stick with unibeast - installation works.
Than I installed the system using mulitbeast.
But after finishing the Sierra installation und rebooting using with the new internal ssd keyboard and mouse aren't recognized at all. But they work perfectly while booting from the usb stick.
I connected the keyboard and mouse through a usb hub - since I have only two usb 2.0 ports and I need one ubs 2 port for the USB stick
what can I do?
this is so strange!
Thanks a lot!

I'm having the same problem. The USB keyboard and mouse don't work if I plug them into the USB 2.0 ports below the PS2 (actually, my first problem was my PS2 keyboard stopped working after installing Sierra). I found that if I plug the keyboard and mouse into a USB 3.0 port (even though they're USB 2.0 devices) they work.

I came across this post looking for an answer as to why the USB 2.0 ports don't seem to work.
