Question about Microsoft Windows XP Home Edition

USB2 Problem Windows thinks My card is USB1.1

I have a problem with a GMU2P-04V USB2 card. I have a K7VAT, VIA KT-133 CHIPSET and ATX Form Factor Main Board. I have the latest BIOS and run XP Pro sp2 which has all the latest updates. There are 4 ports on the card and 2 USB1 ports on the back of the original case. I have tried searching for new driver updates and have installed the 2.1 March 2008 edition which was the latest I could find.
The problem I have Is no matter what Port I use for connecting a USB2 device Windows throws up a pop up saying this device will run faster if you connect it to the USB2 port, and shows 4 empty ports, when in fact they are all occupied. I have the original installation cd with the drivers but XP installs its own drivers before you have a chance to, also the instructions say it the card supports XP but the driver folder on the CD only mentions ME and 2000 editions!
Also in device manager it shows I have an advanced host USB and relevant usb roots installed OK.
I would be most grateful if you could throw some light on this subject as I have been trying to resolve the issue for a number of years now.
Does any one know if my motherboard does support USB2, if not can you buy any external device that will work?

Kind regards Mr B. Hutchinson

    Hello Krenn

    The four USB2 ports on the card are occupied by USB2 devices but windows reports that they are plugged into a low speed device!! In device manager the Highspeed device and drivers are reported as Ok!! The two USB1 ports are built into the motherboard. I have a feeling the motherboard does not support USB2. I have the latest Bios upgrade from AWard but the bios does not mention USB2. The manual for the motherboard says that there are four USB ports, but there are only two external one marked USB 1 and USB 2 I dont think it means (USB2) inside there is an 8 way connector block which is marked as USB2, I have no idea what that is. I have the CD for the card but XP loads its own drivers saying they are better than those on the disc.

    Any help appeciated. Also if the mother board does not support USB2 is it correct that The USB2 card I purchased will not work, I might have a case for a refund as I purchased it from Novatech who sold me the computer and the card.

    Regards Barry

    Hello Krenn

    Thanks for that, I have had this problem for some years now and have not been able to resolve it, I have tried all different forums even the VIA manufacturers themselves and judging by google searches I have done there are hundreds of people out there with the same problem. I have a Cannon scanner which is USB2 when plugged into the card windows says I have plugged it into a low speed hub, I also have a USB2 external hard drive plugged into the card and get the same results also NTL cable modem.

    Where can I purchase these connectors you mention??

    Once again thanks for taking time out for me.

What do you mean when you say that the 4 USB2 ports are all occupied?
when you say that there are 2 USB1 ports on the back of the case: are those ports connected to the motherboard at all?

what devices are you using to test your USB ports? is it possible that those are USB 1 devices?

    ok... if there are 8 pin connectors on the motherboard marked USB2, you would use those by purchasing a little plate with USB2 connectors, and screwing that onto the case. then you would plug wires on the back of those USB2 connectors into the 8 pin connectors on the motherboard.

    If you have a seperate PCI card plugged into the motherboard, with USB2 ports mounted directly on the card, that should work, even if the motherboard itself does not support USB2.

    however, you may have to install drivers specific to the PCI card.

    Once again, what sort of USB devices are you using? if the USB device, like a zip drive or flash memory stick, is only USB1 compatible, then it won't matter what kind of USB port you plug it into.

Before formating, the sound driver was Via AC97 enhanced audio driver. After formating, I cant install back the driver even try downloading it from the internet. It did not work

It might be because, your computer shows your Audio Card as a " unknown device ".

First of all, install the chipset driver.

Then install the audio driver, and it should work.

Also make sure you select the right version of Windows

I dont have USB 2 drivers on my computer, I am on XP service pack 3. I cant update from the device management list as there is no USB2 thing there, it just updates my 1.1 drivers to newer 1.1 drivers.

USB drivers are part of the operating system. But--that being said, you need to have USB2 support on the motherboard.
I suspect that your motherboard does not support that.
You can buy a PCI card that has USB2 ports on it.

No sound device

? mark means no sound driver install or errors in Device Manager. u can check ur mother board cd room or can search ur audio driver in web or below may be ur answer

Question: Where do I locate motherboard sound drivers?
Answer: Users who have motherboards with on-board audio (often with VIA, Realtek, or C-Media chipsets) may have issues with their audio or AC'97 errors in Device Manager. Often this is caused because the operating system has been reinstalled and the motherboard chipset drivers are not installed. To resolve this issue try following the below steps.
Let Windows redetect drivers
If you have not recently reinstalled Microsoft Windows it's possible that your audio drivers are simply corrupt. Open Device Manager and remove all devices under "Sound, video and game controllers" and any "Other devices". Once removed reboot the computer and let Microsoft Windows re-detect the audio drivers.
Motherboard chipset drivers
Reinstalling the motherboard chipset drivers will usually resolve this issue. If your computer came with a Motherboard CD, install the chipset drivers from the CD and the sound drivers if also available on the CD.
If you do not have a motherboard CD, obtain the motherboard chipset drivers from the motherboard manufacturer.
Sound card drivers
If after installing the motherboard chipset drivers you continue to have issues install the sound drivers. We suggest you download the sound drivers from the computer manufacturer or motherboard manufacturer.
A listing of motherboard manufacturers and their drivers can be found on our motherboard chipset drivers page.
