Suppose we want to change the serial number of the above to 00000978. This is the command we will run. It will change the serial number as well as rename the dongle to UAT.

Write new configuration to device [y/n]?


Enter y here and it will rename your dongle. Once complete, unplug the dongle and then plug it back in. Now its serial number is 00000978.
