A8N-SLI Deluxe USB problems

Archived from groups: alt.comp.periphs.mainboard.asus,microsoft.public.windowsxp.general,microsoft.public.windowsxp.basics (More info?)

I have an ancient webcam that I used with my old computer (that
computer only had USB 1.1) and it worked fine. I could get 30FPS video
at 320x240 with my old machine, but when I plug it in to the onboard
USB on the A8N-SLI it refuses to run at 30fps. And if I plug two
webcams in at once, both only run at 15fps and additionally it will
tell me that USB bandwidth was exceeded!

I put in the USB 2.0 PCI card I got for my old machine and tried that
and now I can get 30fps on the old camera and use both with no error
messages.

What gives with the A8N's USB? It claims to be USB 2.0 but doesn't
even have the bandwidth of USB 1.1. I'm not using any more or less USB
devices than I was on my old machine.

The CD that comes with the motherboard says USB 2.0 drivers are not
necessary and to just install Windows XP Service Pack 2, but when I do
I still have a yellow '?' in device manager until I have windows search
for new drivers. Then the yellow '?' goes away but the webcams don't
perform any differently on the onboard USB even after being reinstalled.

    Try uninstalling the device in Device Manager, rebooting, and when it
    detects new hardward point it to the CD that came with the camera. Maybe
    that will work???

    USB 2.0 drivers ARE in the SP2 update, and they DO work!

    They're also in SP1 and they also work.

    They don't work for me.

    Well, you don't know that, the webcam probably isn't USB 2.0.

    How old is this camera? It could be doing something strange on the USB
    bus that the motherboard's controller doesn't like.

    You have hit the critical point, I believe: if the Web Cam is old [more
    than 2-3 years old], it is NOT USB 2.0 enabled. The manual/instructions
    that came with it should be consulted.

    But USB 2 is backwards compatible with most 1.1 devices.

    What makes this particular issue odd is that the 1.1 camera works on a 2.0
    card. It isn't working on the USB ports that come off of the mainboard
    (supposedly 2.0 as well). It sounds like there is something wrong with the
    USB 2 implementation on the motherboard.

    There is also a message about exceeding bandwidth when using the builtin
    USB ports. Another less common event. More often seen with a USB hub or
    other peripheral USB slot (in a keyboard, on a monitor, etc). If the main
    USB controller isn't getting enough power... how is the USB card managing
    to deliver enough?

    Sounds like something is not quite right with this board but this is not my
    field of expertise and am guessing.
