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

Fail to Get MOBITEK S80 to Work in USB port in VirtualBox

This method mentioned in https://www.wintips.org/how-to-setup-usb-on-virtualbox-guest-oracle/  was used to test the USB driver of MOBITEK S80 3G Modem in the virtual machine (Windows Server 2012 64-bit)

After installing Extension Pack in VirtualBox, USB 2.0 and USB 3.0 shown in the USB list

When virtual machine was started, the “Sierra Wireless” device was shown in the list:-

The COM PORT (COM6) appeared in “Device Manager”:-

However, in Hyper Terminal the “AT-OK” test could not be performed because it seems like the Hyper Terminal only catch the physical COM PORT of the MOBITEK S80, but the connection is not actually established with the modem. Nothing can be typed in Hyper Terminal to test the connection.

 

The same problem happens in Linux Mint running in VirtualBox

  • VirtualBox version: 6.1
  • OS in virtual machine: Linux Mint 17 ‘Qiana’ Cinnamon 64-bit

Mobitek S80 that attached to Linux Mint running in VirtualBox can be detected when running the “dmesg | grep tty” command in Linux Mint’s Terminal

But each interface from “ttyUSB0” until “ttyUSB4” which MobitekS80 is attached to cannot be tested with AT command in CuteCom. CuteCom will be frozen when the AT command was entered.
