I am trying to connect ZTE MF 190 in Linux based OS. But the problem is it is automatically modeswitching without entering any USB Modeswitch command and I am not able to mode switch after that

This message appears as soon as i connect Dongle without any need of any usb modeswitch command and only ttyUSB3 works for sending AT commands . Other Ports are not working at all
lsusb shows below output

I tried using below modeswitch command as soon as i connect dongle
usb_modeswitch -v 0x19d2 -p 0x2000 -V 0x19d2 -P 0x2003 -s 20 -M 55534243123456702000000080000c85010101180101010101 000000000000
But no use since its switched already.
I tried sending below AT commands for disabling CD-ROM Mode and convert to modem mode
AT+ZOPRT=5
AT+ZCDRUN=8
But beahviour is same . Please let me know if there is any method to make This dongle work
