Objective: to use AT command to rename “Sierra Wireless” to “MOBITEK” so that all the 4 COM ports will display “MOBITEK”

Result: after using the “AT+WUSB” to change name to “MOBITEK”, the 4 COM ports in device manager still show  as “Sierra Wireless” .

In addition, there is no AT command to remove the other 3 COM ports, “CNS”, ‘DM” & “NMEA”
