Thanks for keeping me up to date on this topic, which is still totally relevant to me. I looked at the series, but it does not seem to be addressing the problem with USB host not detecting new devices when VBUS is not directly connected, e.g. in the Colibri imx6ull SoM. Xu, do you confirm the series at the link is _not_ solving the problem being discussed here? Best regards, Luca -- Luca Ceresoli, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
