Someone here who has Linux knowledge and a GoPro / Sony Action camera (like AS-30) who can help me with the output of running lsusb with the camera connected via USB to the computer:

lsusb -d <idVendor>:<idProduct> -v

I am interested just in the Device Descriptor “iSerial” field:

Example output:
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  <-- Some manufactures make this unique for every device/some don't include it
  bNumConfigurations      1
  Configuration Descriptor:

My config will have multiple identical cameras connected to the same computer, and I want to know if I can use the “iSerial” number to uniquely identify each camera. I am not interested in receiving an “iSerial” number, just if you can confirm that this number looks unique.

I have run lsusb -v for my USB-connected GoPro Hero 4 Silver. The returned iSerial indeed looks like a (unique) serial number. The returned number is composed of a single capital letter followed by 13 digits.

Unfortunately, I don’t have multiple GoPro cameras to confirm that they actually all return different numbers. I neither have a Sony AS-30 to check there.

EDITED to add: I have just found the same serial number returned by lsusb on a sticker in the battery case of the camera. So it indeed seems to be a unique serial number.
