USB 3.0 only good for storage devices? Only? Asus MOBO manual states such.

I'm reading the owner's manual of the new Asus Maximus VII Hero, and with regard to USB 3.0 ports it states the following on page 2-13:

__________________________
* Due to USB 3.0 controller limitation, USB 3.0 devices can only be used under Windows OS environment and after the USB 3.0 driver installation.

* USB 3.0 devices can only be used as data storage only.

* We strongly recommend that you connect USB 3.0 devices to USB 3.0 ports for faster and better performance for your USB 3.0 devices.

* Due to the design of the Intel 9 series chipset, all USB devices connected to the USB 2.0 and USB 3.0 ports are controlled by the xHCl controller. Some legacy USB devices must update their firmware for better compatibility.

Does this mean I cannot plug a mouse, printer, or keyboard, into a USB 3.0 port? Only storage devices???

What's the purpose of having all these USB 3.0 ports if they can only be used for external hard drives?

Your mice and keyboard will work fine, as long as you install the drivers.. What it says " USB 3.0 devices can only be used as data storage only." means that there are no usb 3 mice/keyboard, which is because they dont need the extra speed, only storage devices need usb3 so only strage devices are usb3. However USB 3 is ALWAYS backwards compatible with USB 2. Your devices will work..

You most certainly can plug whatever you want into a USB 3.0 port, USB 3.0 is backward compatible. However, the ports will not function at all until you install the proper drivers. It's always best to keep your mouse/keyboard in USB 2.0/1.1 ports for that reason. I believe that you have misunderstood what you read, USB 3.0 devices will only operate at 3.0 speeds when plugged into a 3.0 port using a 3.0 cable otherwise they will run at 2.0/1.1 speeds. At present I've only seen storage devices with USB 3.0 ports as such things as keyboards, mice, printers, etc. don't benefit from the greater speed.

USB 3 drivers are included in Windows 8.x. Any USB3 port should work automatically in Win 8 the way USB2 ports do in earlier versions of Windows.

The purpose of USB 3 is to speed up storage devices, so it's true that most other devices won't care about the difference between USB 2 and 3

Keyword being "should". I've come across hardware (albeit somewhat older) that didn't function without additional drivers.

Thanks much to everybody for responding. Vortical picked up on the one bulleted point of Asus that had me stumbling.

Thanks all.
