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.
