Do the all USB ports on your Motherboard work correctly? You said your mouse works on USB, if you unplug it and plug in your IPOD or camera does windows see the devices? The PCI USB card, is it recognized in device manager? Any other available PCI slots you could try and plug the PCI card into? As a last resort you could just stay USB 1.1 (which would suck but better it work slow than not at all) and just drop a USB hub into the slot where your plugged in your mouse.
