Wireless/Wired Keyboard & Mouse does not work on login screen
This is a clean install of Windows 7 Pro x64. I've run out of ideas. Here's a list of what I've done thus far,
Keyboard/Mouse works flawlessly in UEFI BIOS but once I arrive at the password login screen it stops working
1) New RAM
2) New Mobo
3) Replaced fresh batteries on my Logitech MK550 kb/mouse combo
4) Checked BIOS settings for Legacy USB
5) Updated BIOS
6) Updated firmware on Samsung 850 EVO
7) Tried every USB port (2.0 & 3.0, front and back)
Here's the catch, once I unplug my WiFi receiver (ASUS USB-N53) keyboard/mouse works like normal, plug it back in, stops working at login screen.
What exactly is going on?
