Did you set the configuration to 0 as well? If you tried to echo 0 to the bConfigurationValue file, did it succeed, or did it spit out an error? Do you still have other USB devices attached to the system (these include USB mouse and keyboards). If possible, try removing those as well, and using the webcam. You may have to ssh into your box to do this. Otherwise, I'm really not sure what you can do to get the camera working under the Intel xHCI host. There's just not enough bandwidth for it. I'll take a look at the lsusb output you gave me, and try to see what bandwidth the camera is asking for.
