ZTE HSPA+ Modem stop connecting

Post by hopperman » 19 Sep 2022, 18:08

Hi, I have USB GSM modem ZTE HSPA+ Turkcell VINN MF667, whose vendor-product ids : 19d2:1405. While I can connect, it fails. I replug the modem, go to its internet browser router interface from and interface is working. Green light is blinking. After entering PIN, it goes Connect menu. However, when I pressed "Connect" button nothing happens, it is not connecting. I tried :

Code: Select all

sudo usb_modeswitch -v 19d2 -p 1405 -RWs 3
It says :

Code: Select all

Take all parameters from the command line

 * usb_modeswitch: handle USB devices with multiple modes
 * Version 2.6.1 (C) Josua Dietze 2017
 * Based on libusb1/libusbx


DefaultVendor=  0x19d2
DefaultProduct= 0x1405
Success check enabled, max. wait time 3 seconds
