Hi Tom, and welcome to the DCT Forum. 
The fact that neither your wireless nor wired mouse and keyboard are recognized is a tad unusual. Is it a UEFI machine or an older BIOS machine? Are you certain the mouse and/or keyboard are plugged into USB 2.0 ports and not USB 3.0?
Cheers... Jim

According to the SIW report, USB 3.0 ports are included with the motherboard. USB 3.0 ports are usually blue, have a look at the back and front USB ports and see if there are any that are blue. Then, make sure the mouse and keyboard are NOT plugged into the blue ports.
Also; are both the Microsoft mouse and keyboard driver and the Microsoft Mouse and Keyboard Center software up-to-date?
You may also need to go into BIOS and see what settings there are relating to USB, mouse, and keyboard.

These settings in BIOS (XHCI and EHCI) are designed to overcome an operating system's shortcomings regarding USB support and management.
For example: XHCI (Extensible Host Controller Interface) is Intel's USB 3.0 controller (driver). The controller was introduced by Intel for USB 3.0 enabled machines running operating systems without native USB 3.0 support (which includes Windows 7). Native USB 3.0 support was introduced in Windows 8.
Not sure if these settings have anything to do with the issue or not but, considering a fresh install means you are working outside of an existing OS and relying solely on BIOS, it may well be the case.
I would try changing those settings in BIOS to see if they make any difference. First; try setting EHCI Hand-off to Enabled. If that doesn't work, try setting both to Disabled.
Let us know how you get on.
