Contrary to a USB serial number, these identifiers9 are writable and can be set per CAN interface. This means that10 if a USB device exports multiple CAN interfaces, each of them11 can be assigned a unique channel ID.12 This attribute provides read-only access to the currently13 configured value of the channel identifier. Depending on the14 device type, the identifier has a length of 8 or 32 bit. The15 value read from this attribute is always an 8 digit 32 bit16 hexadecimal value in big endian format. If the device only17 supports an 8 bit identifier, the upper 24 bit of the value are18 set to zero.19 20
