Contrary to a USB serial number, these identifiers 9 are writable and can be set per CAN interface. This means that 10 if a USB device exports multiple CAN interfaces, each of them 11 can be assigned a unique channel ID. 12 This attribute provides read-only access to the currently 13 configured value of the channel identifier. Depending on the 14 device type, the identifier has a length of 8 or 32 bit. The 15 value read from this attribute is always an 8 digit 32 bit 16 hexadecimal value in big endian format. If the device only 17 supports an 8 bit identifier, the upper 24 bit of the value are 18 set to zero. 19 20
