Windows 7: USB 3.0 Ports run as USB 2.0 Only

04 May 2012   #1

Windows 7 Home Premium x64
USB 3.0 Ports run as USB 2.0 Only

Hello All1

I just bought me a 1TB USB 3.0 External HDD.

The LED glows green when in USB 2.0 mode, and Blue when in USB 3.0 mode.

When I boot my computer, the light is Blue; that is, until Windows starts up, then it goes Green showing that it has reverted to 2.0 mode.

I have run out of ideas, except one. I was wondering if changing the BIOS setting to non-Plug 'n' Play would let BIOS allocate all the ports, etc., instead of Windows.

Will this 'break' Windows? I really don't want to have to do a re-install.

Or if anyone has other ideas, please let me know.

What I have done so far is:
  • Uninstalled/re-installed the 3.0 drivers (I made sure I have the latest)
  • I've tried different settings in BIOS to no avail
  • I've Googled and scoured this forum to no avail

I read somewhere on this forum, I think, that I should have the same number of USB Root Hubs as Controllers. That is not the case.

Here's a shot of my DM:
