我感兴趣的领域是从以下输出的iSerial： lsusb -d <idVendor>:<idProduct> -v
非唯一iSerialNumber的示例输出：
Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 239 Miscellaneous Device bDeviceSubClass 2 ? bDeviceProtocol 1 Interface Association bMaxPacketSize0 64 idVendor 0x0402 ALi Corp. idProduct 0x9665 Gateway Webcam bcdDevice 0.09 iManufacturer 3 iProduct 1 iSerial 0 <-- Three string descriptors exist to provide details of the manufacturer, product and serial number. There is no requirement to have string descriptors. If no string descriptor is present, a index of zero should be used. bNumConfigurations 1 Configuration Descriptor:
据我所知，iSerialNumber并不总是包含一个唯一可识别的string值。 例如，Iphone和Ipad包含这些信息，但是我testing过的一些其他设备没有这个价值。 具有string描述符的USB标准并不是强制性的。
拥有GoPro的人可以告诉我它是否有序列号的string描述符吗？
我还没有相机。
我回来了iSerial 3 123456789ABC ，我用Hero3 Black Edition进行了测试
