I have recently installed an external freecom 160gb hdd to my laptop. I am
running XP with sp2.

My laptop has 3 usb 2.0 slots of which the enhanced usb drivers are installed.

When i plug in my hard disk in get the error message

"this usb device can perform faster if you connect it to a hi-speed usb 2.0
port"

If you click the baloon it takes you to a screen that showws you a list-
which looks like:

+ SiS PCI to USB Enhanced Host Controller
+ USB Root Hub (6 ports)
Unused Port
Unused Port
Unused Port
Unused Port
Unused Port
Unused Port

AsI said earlier I have 3 physical ports not 6! and they are all saying
unused- but the keyboard I am typing this on and the mouse i am using are
both plugged in?

The device manager shows no problem with any devices!

I flattened my PC, and reinstalled everything agin and its still not
working! The hard drive works perfectly fine in usb 1.1 though!

Note: originally the ports worked fine!

Whats the problem? Could it be a hardware fault?

someone please help! its driving me nuts!

Many thanks for your time

Disconnect the USB mouse/keyboard.

Remove all USB Root Hubs/ports
Remove the USB Enhanced Host controller
Reboot

Access the laptop's BIOS and make sure that USB ports are set to USB 2
and/or Auto. I have seen PCs where you can tell the BIOS which level of USB
to use.

Restart XP. XP should not re-load the USB controller and USB Root hubs.

Hi there

I have exactly the same problem on my HP d530 computer : there are 6 USB
ports which should work in USB2.0
But when I plug my external USB 2.0 HDD, it says the same as cplhusher :
"this usb device can perform faster if you connect it to a hi-speed usb 2.0
port"

And then show me a list with 8 unsed USB 2.0 ports ( I remind that my
computer has only 6 physical ports!!)

I have tried everything : flash the Bios, update chipset drivers with Intel
utility etc... Nothing change!!

Can someone help us to solve this???
