Functionfs requires MtpServer to write descriptors before the device can be configured. This adds a new configure call that will occur only when functions are changed (new argument added to updateUsbStateBroadcast for this) and be called after sys.usb.config is changed but before the waitForState call to ensure compatibility with configfs devices. Bug: 30976142 Change-Id: I7e94a5847d3b19c0fd75139e1b15a3f2a1cea01d Test: Manual
