| Description: | |
| PEAK PCAN-USB devices support user-configurable CAN channel | |
| identifiers. 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. | |
