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