This is where stuff gets weird for both Windows 8 and Windows 8.1. This was discovered when I was searching for Joystick UID's in Windows 8 based on Ranak's suggestion. If it says ' Allow the computer to turn off this device to save power' and is checked then please UNCHECK it You have to turn OFF the manual power savings one by one to all USB Devices/Compositive Devices and the all the USB Root Hubs (this is v.important). Please see your HID Devices, USB Input Device and USB Root Hub Devices - They are STILL set to Suspend. The power management on USB devices is set to Selective Suspend Honestly, that setting does not disable USB selective suspend in Windows 8 (this is for Windows 8 only), like it promises. Windows 8 Solution - (FSX / Prepar3d 1.4)ġ) Make sure power management features are off or set to highĢ) Most important setting is USB Selective Suspend Setting is Disabled (we all knew this) OS - Windows 8 Pro Clean install / Windows 8.1 Clean Install Video: New XFX 6970 2GB with latest ATI drivers
