7 PEAK PCAN-USB devices support user-configurable CAN channel
8 identifiers. 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
