title: libusb: get Device by serial number
body: <p>libusb lets you find a device by it's vendor and product ID. But what if I have several devices with the same VID and PID attached, and want to get a handle to one of them by knowing it's serial number? There is a <code>libusb_open_device_with_vid_pid</code>, but no <code>libusb_open_device_with_serial</code> or similar. Would I have to crawl though the full device list (<code>libusb_get_device_list</code>) or is there a more convenient way?</p>
