To make a long story short I've had to disable xHCI (disable USB 3.0 functionality) in BIOS because my Saitek x52 Pro joystick refuses to work when xHCI (USB 3.0) is enabled. It is to the point where the joystick causes Windows 7 to refuse to boot or freeze, and this happens everytime.


I just received my new Ducky Shine 5 keyboard in the mail today. The Ducky Shine keyboard is full of pretty LEDs and requires USB 3.0 level voltages for full LED functionality.


My Ducky Shine keyboard is plugged into a USB 3.0 port, but my USB 3.0 port has been downgraded to USB 2.0 functionality due to my needing to disable xHCI.


My question is, since I disabled xHCI is my USB 3.0 port now putting out only USB 2.0 level power? I know by disabling xHCI I have reduced my USB 3.0's port to USB 3.0 speeds, but have I also reduced the 3.0 port voltage output to a 2.0 level?


Thanks for all the help.
