Ok, I'm really not sure what's going wrong here. The host controller is rejecting the configure endpoint command with a completion code of 0x11, which is a parameter error. But I've double checked the input context, and everything looks correct, according to the 0.96 xHCI spec. That checking is attached. Do any USB 2.0 devices work under this host controller? Maybe something that has a different endpoint type than a bulk endpoint, like a webcam or mouse? Sarah Sharp
