The xHCI 1.0 specification is now available for anyone to download at: http://www.intel.com/technology/usb/xhcispec.htm They haven't posted the 0.96 specification yet (which is what current shipping hosts and the xHCI driver conform to), so I'm going to have to poke some people. But now everyone can actually read about TRBs, set TR deq ptr commands, and the like. :) Sarah Sharp -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
