Last I heard, xHCI debug support was a logo requirement from Microsoft for Windows 8 and above, so I would have thought that most vendors would have implemented it by now. I know Synopsys put a lot of effort into making sure it works in our IP. Or did Microsoft relax that requirement at the last minute? -- Paul -- 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
