Do you have any hint for me? > It means your OTG VBUS does not lower than BSV (B SESSION VALID, 0.8v) after plugging out Micro-B-TO-A cable. Two possible reasons: 1. You have not gpio control for vbus toggle when role switches. 2. Your hardware has some problems that the vbus can't lower than 0.8v. > btw. what is the plan about cleaning up and upstreaming all these patches > we > have here? Is anyone working on it?
