Hi, Sometimes I was encounterd an issue that auto-wakeup at second time from S3 if use mouse to wakeup OS at first time. Then I reset the port which current status is connected in PORTSC during pci resume process in host controller driver (xHCI), this issue doesn't happen. But resetting all connected port is not good. So have you any ideas to distinguish that the device class is mouse which attached on port in host controller drivers?
