Hi there

First thing to try is this :
go into device manager->USB Controllers->USB Root Hub->properties->power management and uncheck the box labelled 'Allow computer to turn off this device to save power'
Click OK & reboot.

If that doesn't work, try refreshing the USB stack :
Make sure you don't have any usb devices connected
Go into device manager & remove all of these in the following order :
1. USB devices (except usb mouse if you use one)
2. HID and/or composite usb
3. USB root hub
4. usb host controller

Reboot the laptop & let windows redetect & reinstall the usb controllers.
Then try connecting a usb device again.

Do you know if you have an SIS USB chipset by any chance?

Stevedude, have you tried the suggestions I made in my previous post yet? If so, did they make any difference?

If they didn't then follow the link below, look under SIS in the list & download the file usbdetect.exe.

http://www.usbman.co...and Patches.htm

This is a WinXP only SIS chipset patch that resolves problems with SIS USB controllers in XP.

Give a try & let me what happens
