Some drivers may need to be updated, uninstalled, or reinstalled on your computer in this case. To expand the USB drivers menu and see which drivers require actions, tap on the + before the driver headers. Drivers with an X mark, question mark, and exclamation mark on them are the ones that require appropriate actions.
