Contrary to a USB serial number, these identifiers 9*6d02f6daSLukas Magel are writable and can be set per CAN interface. This means that 10*6d02f6daSLukas Magel if a USB device exports multiple CAN interfaces, each of them 11*6d02f6daSLukas Magel can be assigned a unique channel ID. 12*6d02f6daSLukas Magel This attribute provides read-only access to the currently 13*6d02f6daSLukas Magel configured value of the channel identifier. Depending on the 14*6d02f6daSLukas Magel device type, the identifier has a length of 8 or 32 bit. The 15*6d02f6daSLukas Magel value read from this attribute is always an 8 digit 32 bit 16*6d02f6daSLukas Magel hexadecimal value in big endian format. If the device only 17*6d02f6daSLukas Magel supports an 8 bit identifier, the upper 24 bit of the value are 18*6d02f6daSLukas Magel set to zero. 19*6d02f6daSLukas Magel 20
