Julius Werner f7f6f008f7 libpayload: usbhub: Don't clear PSC unless it was set ... The current USB hub code always clears the port status change after checking it, regardless of whether it was set in the first place. Since this check runs on every poll, it might create a race condition where the port status changes right between the GET_PORT_STATUS and the CLEAR_FEATURE(C_PORT_CONNECT), thus clearing the statrus change flag before it was ever read. Let's add one extra if() to avoid that possible headache.
