    We had a user whose USB memory stick wouldn't install properly when connected to a Compaq EVO N800c laptop. XP would prompt for the driver, but in XP, that shouldn't happen. I've tried the USB memory stick on other XP laptops and they all "saw" the device and the appropriate "drive" showed up in the My Computer window. In addition, it doesn't react to other USB connections in a normal fashion, though it's apparent that the laptop/XP does sense when a USB device has been connected to the laptop.

    So, in my finite wisdom, I decided to simply delete any USB controllers or Root Hubs listed in the Hardware Manager listings.

    Upon the reboot of the laptop, I had hoped that XP would be smart enough to find the USB controller and hub/connectors and install the correct drivers. Well, it came up with asking for the drivers in another media because it didn't find it within its XP files. So I wound up doing a search for "USB*" on the hard drive and finding all sorts of drivers sitting in the usual directories, so for each device that was showing up as a yellow device, I pointed XP to look in the appropriate subdirectories where the old USB drivers/inf's/etc were, and it started to install these new found USB-related devices.

    The only one that it doesn't find is the USB 2.0 Root Hub device, and I have no idea how to get XP to recognize USB 2.0 functionality now.

    I did do the XP USB 1.1/2.0 patch from the Windows Update site, and I have all of the other Windows Updates installed on the laptop as well.

    At this point, the laptop is where it was earlier (minus a USB 2.0 Root hub device), where if you connect a USB device, it'll sense something is there, but it'll prompt you for the drivers, or it just doesn't react like a normal XP installation seeing USB devices (like connecting a digital camera and using the Canon Zoom software to access the memory card via a USB cable and create a drive to get to the photos on the memory card.

    So, any other ideas?

    Does that model Laptop actually have a USB 2.0 compliant port or is it legacy USB 1.1 (USB 1.0)? If it only has USB 1.x there is no way to add USB 2.0 to it unless you buy a Third-Party peripheral like a PC Card (PCMCIA) USB 2.0 card which has it's own controller in it.

    Yes, the Compaq N800c comes with USB 2.0 ports.

    I'm almost at a point where I think something is wrong with the USB ports/controller that's built into the system board.

    Anyone know how to force XP to install SP1 over itself (if SP1 has been installed before).

    What about trying a windows repair install over the old install? I've found that sometimes its faster to redo it then try to find the problem and fix it.

    Windows XP sp1

    That'll get you the servicepack 1 for seperate install outside of Windows Update.

    Have you tried re-installing the Compaq USB2.0 drivers? Might have to go over to HP's site for those

    Patrick,
    Here is some info that may help. You might try the Intel Chipsets USB Driver Setup Utility available here:
    http://www.americanpredator.com/support/drivers.html
    The usb20 setup utility may do the trick. If you need to download the USB 2.0 drivers, they are available on the Intel developer site for your motherboard:
    http://developer.intel.com/design/motherbd/gendrive.htm
    Intel provides a utility to determine what chipset you have, if you do not know:
    http://support.intel.com/support/chipsets/chipsetid.htm
    If none of the above works, you may need to download the INF update utility (INFINST.exe). This utility installs INF files that inform the operating system how to properly configure the chipset for specific functionality such as USB and AGP. It's also available in the Intel download section.
    Also, here's a MS KB article which list the correct versions of the 2.0 drivers:

    Thanks for the suggestions, I'll give them a try in the coming week after Thanksgiving when I get my hands on the laptop again.

    I had a similar problem on a Dell a few months back. Installing the drivers from the Intel site worked for me.

    Good luck!
