If anyone has any objections, please let me know. ------------------ From: Michael Grzeschik commit 2bac51a1827a18821150ed8c9f9752c02f9c2b02 upstream. The delayed_status value is used to keep track of status response packets on ep0. It needs to be reset or the set_config function would still delay the answer, if the usb device got unplugged while waiting for setup_continue to be called.
