It seems its a problem of this model. When my nuc is off, it will starts after some action on the usb. Moving the mouse, put in or out a usb-device.
Glamamit89, I’m sorry to hear that you are also experiencing this behavior. We were able to test this feature using a remote control and CIR worked just fine on a Windows environment.
The following thread contains information about this behavior when using OpenELEC.
At this point I recommend you to check if you have the latest BIOS and drivers available for this product.
