How install GSM modem?

Post by gumis_148 » 2019/11/25 13:45:47

I want to install the Huawei E3131 GSM modem on a Centos virtual machine that is on Hyper-V (Windows 10). In Windows and Centos, the modem is detected as a CDROM.

I wanted to do according to the instructions:
https://techexpert.tips/ubuntu/send-sms ... mand-line/
but I can't disconnect the modem(CDROM) because it will disconnect me from Hyper-V.
Below are the commands:

Code: Select all

[root@localhost ~]# df -h

You'll need to run usb_modeswitch to flip it from CD-ROM mode (for the Windows drivers) and into modem mode.
CentOS 6 will die in November 2020 - migrate sooner rather than later!
CentOS 5 has been EOL for nearly 3 years and should no longer be used for anything!

I can't switch because I don't know the modem ID. I can only assume based on other tutorials.

Code: Select all

[root@localhost ~]# echo "12d1 1506" > /sys/bus/usb-serial/drivers/option1/new_id
[root@localhost ~]# usb_modeswitch -v 12d1 -p 14fe -V 12d1 -P 1506 -M "55534243123456780000000000000011062000000100000000000000000000"
Look for target devices ...
 No devices in target mode or class found
Look for default devices ...
 No devices in default mode found. Nothing to do. Bye!

[root@localhost ~]# lsusb
[root@localhost ~]#

Code: Select all

[root@localhost ~]# usb_modeswitch --version

 * usb_modeswitch: handle USB devices with multiple modes
 * Version 2.5.1 (C) Josua Dietze 2017
 * Based on libusb1/libusbx

 ! PLEASE REPORT NEW CONFIGURATIONS !

You need the usb ids reported by lsusb for it's current state.
