[ 485.687201] usbserial_generic 1-1.1:1.2: The "generic" usb-serial

I use a Kernel v.3.16.0 in Debian.
I'm tring to use my usb mobile broadband device named
MT6225
2020:4000 (vendor:product)
I'm loaded usbserial typing:
modprobe -v usbserial vendor=0x2020 product=0x4000
Using wvdial to connect, I use some AT commands
The first two are [OK] but with the latest say: "bad init string"
Try NetworkManager instead, it should give you a direct ethernet
connection via cdc_mbim.
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+cgdcont=1,"ip","ibox.tim.it"
cmds should usually be upper case so cgdcont might be rejected by the
dongles firmware, not that I think it will make any difference in your case.
I have recently come across a couple of USB dongles based on Mediatek
phone/ phablet chips and they seem to have the serial dialup function
disabled in their firmware if they have a cdc_mbim interface. Other
dongles based on the same chip but without the cdc_mbim direct ethernet
interface have a working ppp functio nin the firmware.
After my signature, there is the output before and after the modprobe
command
thank you
regards
