If you are unable to get past initial install, see this step-by-step guide: How to Install Windows 7 with only USB 3.0 Ports
The example in the guide is of an installation of Windows 7 Pro, so it should be pretty straight forward just following that. This worked well for me.
Thanks for the info. It appears that the method you suggested does not apply to the chip set in the NUC5CPYH. I am extremely curious why the Intel Windows 7 USB 3.0 Creator Utility does not work. When you run the Utility on the prepared Flash Drive image, it reports that it has installed the USB 3.0 drivers, but when you install Windows 7 from the flash drive, the USB 3.0 drivers do not install and the keyboard or mouse are not recognized. There is no way to continue the install past the first screen. There is a supposed to be an internal header on the board with 2 USB 2.0 ports, but I have no idea where to get anything that would connect to the sub-miniature connector and provide accessible USB 2.0 ports.
Thank you for contacting the Intel® Communities.
I would like to verify if the requirements for this process are being met, this may be affecting the procedure:
-You have a valid copy of Windows 7 on ISO or DVD.
-You have Administrator access to another working computer (the Admin system) with Windows 7 or later to follow these steps.
-You have download and unzipped the Windows 7 USB 3.0 Creator Utility.
If they are met, let make sure you have the latest BIOS in your system; Also if possible/available disable xHCI from Advanced>Devices>USB
