Windows 7: This device can run faster...USB problem

Hello,



Since a couple of weeks a get the message "this device can run faster" when I plug a external HD or USB stick in the USB ports of my laptop.
Its not only a warning, the transfer speed is also a lot slower as it used to be...
Now, cannot recal when it started exactly and if I did something special...
My laptop is an ASUS UL 80V running on windows 7 64bit.
If tried updating the intel chipset drivers, no help....
Then I replaced the internal HD with an SSD HD and made a complete fresh Windosw 7 install just to find out that my problem still exists.
Again updated my intel ICH9 chipset drivers but without result...so it does not look like a software problem? Anybody an idea/solution?

I was getting that message after SP1, not sure if that applies to you as well.

I just uninstalled the usb drivers and when windows reinstalled them, the problem was gone.

Here's another thread marked solved, This Device Can Perform Faster

Tried that several times...no help and same problem after installation of SP1...
a while ago I "lost" my buildin webcam also...not such an issue but I think that the problem started then...

Have you checked the settings in the BIOS?

As mentioned in the last post here,

This Device Can Perform Faster

Checked my BIOS, dont have any settings concerning USB...

Well, that's all I have. Sorry.

If you could fill in your System Specs,

System Info - See Your System Specs

I'm sure it will help those with other ideas.

As I know, the latest USB devices (USB3) can transfer at a rate of 5 Gbit/s whereas USB2 does it at 480 Mbit/s and USB1.1 does it at 12 Mbit/s . If your USB port is a older one, a latest USB device will pop this message up .

This laptop is a bit more than 1 year old and has never generated this message and always had "fast" USB transfers...
I have USB2 ports...I dont care about the msg(easy to get rid off), but the lack of transfer speed does gets me crazy...

It could be caused by the following.... If an external hdd is removed incorrectly, the next time it connects, the latency caused by a sort of file check can cause the system to think it is a lower usb speed than it should be. Try a checkdisk on such a hdd, it will take a long time.... When finished, correctly remove. Next time you plug in, it shoul be back to normal speed.

Did you try to set on Write Caching (Better Performance) - in Device Manager > Properties of the device > Policies.
