Linux 使用iSerialNumber USB设备描述符唯一标识GoPro摄像头
我感兴趣的字段是iSeries,其输出为:Linux 使用iSerialNumber USB设备描述符唯一标识GoPro摄像头,linux,usb,udev,gopro,lsusb,Linux,Usb,Udev,Gopro,Lsusb,我感兴趣的字段是iSeries,其输出为:lsusb-d:-v 非唯一iSerialNumber的输出示例: Device Descriptor: bLength 18 bDescriptorType 1 bcdUSB 1.10 bDeviceClass 239 Miscellaneous Device bDeviceSubClass 2 ? bDeviceProt
