Hi
I'm getting the "USB 3.0 This device can perform faster. This USB Mass Storage Device can transfer information faster if you connect it to a Super-Speed USB 3.0 port" message even though the external disk is connected to a USB 3.0 port with a USB 3.0 cable.
Any hints?
Thanks
Try a different port or cable. A USB port has different pins for USB 3 and USB 2, so if there is a problem on the connection for USB 3 it will try the USB 2 circuit. Could also be a driver problem.

Hi there .. For some reason this can happen with Windows 7 .. Best advice i think is just ignore it ...
USB 3.0 computer ports are blue. USB 3.0 cables are either marked blue OR have initials SS on the female connector end of the 3.0 cable. Make sure your connection is right. (And, of course) it's a 3.0 device, i assume.
Connect directly to the computer. Not through a hub
Some MOBOs have one USB 3.0 port that is faster than the others; I ran into that with my new notebook. It has two USB 3.0 ports. One will give me the message saying that the other would be faster (which it was when I tested them).
Other MOBOs use a USB 3.0 booster of some sort that is tied to specific devices.
Thank you all for your helpful replies. The two 3.0 ports tried are definitely 3.0 and cable and external drive are 3.0 too. The speed I am getting on backups is between 3 and 400 Mb/s.
All a device needs to do to be able to claim it's USB 3.0 is be a bit faster than USB 2.0's upper limit.
Every USB controller has a root hub. Each root hub has one or more ports.(The controller + root hub + root hub ports are all on the motherboard). Root hub ports are NOT the same as the computer ports you see on your machine and what you plug your device into.
(In general), when you plug a USB device into the computer port, Windows + firmware dynamically decide which controller/root hub/root hub port it connects to. Bad (wrong) decisions can occur for different reasons.

You should verify what your 3.0 device is actually being to connected to on the motherboard. Download USBTreeView. Unzip and run either the 32 or 64 bit version depending on if you're running 32 or 64 bit Windows. In TreeView, root hub ports are indicated with an H ( for a hi-speed hub port) or (S super-speed hubport).
Post a snapshot of the left side of the display (the visual "tree view") to show us what it's being connected to.
@LadyFitzgerald
You may find this a curious exercise as well. Use USBTreeView to see what type of hub ports your 3.0 device connects from each of your 2 computer ports.
@ComputerGeek, thank you! I rebooted first and, lo and behold, no longer got the warning. I attach the screenshot which now seems to show all is correct. This seems reasonable if the USB port can be reassigned dynamically. If I transfer a large file, I'm getting speeds of about 110-120 Mb/s. Is that a normal value?
