NOTE: The i2ctool does not automatically scan multiple MUXed segments. Before scanning, you MUST set the MUXes to
select the devices you want to see on the busses. By default, the i2ctool scans the i2c devices from the root MUX where it
sees the list of devices directly connected to the CPU MUX. The default scan function scans all connected busses. By specifying
a bus, you can limit the scan to one bus. In the scan data,
RR indicates a reserved address which is not used for any devices and
UU indicates that the device is busy or mapped to the OS.
