Having no other choice I finally purchased this modem and fortunately works fine at high speeds. I noticed that operates differently of other modems. It is an ethernet network on usb in contrary with other which are mobile broadand network. see :https://www.draisberghof.de/usb_modeswitch/bb/viewtopi...

Hi all, I use a zte 3g usb modem for connecting to the internet which works fine. 1) Now I need to buy a usb 4g (/5g) modem. Mark and model is ZTE MF833U1, available in my region. I wonder what are the possibilities not to be detected by OS (Xubuntu 20.04) and so will not be useful, This modem is pr...

Unfortunately no success, i will resume as following. Around 3 months ago i downloaded from lubuntu site and install a lubuntu version 16.04.6 on a usb drive. This is exatcly the same as the updated version on April 2019 installed on dell, with kernel 4.15.0-45 The result was the same and the modem ...

Sorry Josh, i' m not so advanced. I will try to find the device conf file and come back here

Here is the workaround about what i did, in case something is wrong. -first i created an empty file '19d2:2000' as follows: 'sudo -i leafpad /etc/usb_modeswitch.d/19d2:2000' -then i pasted the content of the correct(lenovo) usb_modeswitch.conf file and saved it. It's content is the following: ------...

Sorry, wrong typing. I entered it correctly, 19d2:2000' and i copied/pasted the text from the lenovo usb_modeswitch.conf file
I will see the log again and come back with the content.

There is no 19d2L2000 in usb_modeswitch.d folder, so i created one and pasted the content of the lenovo conf file, but it doesn't work either,
unless i' m doing something wrong during the proccedure.

I' m now with the 18.4 version that is ok.
I tried to possibly find what's going on, but never mind.

I will try to see if it works.
Thank you very much Josh.

Thank you for your response. Do you mean that if i add to StandardEjec=1 this will work ? Last time i downloaded a new 16.4.06 iso, burned it to a dvd and tested live without installing. The result was the same in both machines. The modem was not working. It seems someone from Lubuntu maintainers mi...

Is there something to do with this content

For comparison, i also post here the usb_modeswitch log from the Lenovo machine (as above) where k 3565z is working, . USB_ModeSwitch log from Thu Jun 6 08:41:07 2019 Use global config file: /etc/usb_modeswitch.conf Started via systemd Raw args from udev: 2-1 Bus ID for device not given by udev. Try...

I finally found the file and the content is as follows. USB_ModeSwitch log from Thu Jun 6 07:58:58 2019 Use global config file: /etc/usb_modeswitch.conf Started via systemd Raw args from udev: 2-3 Bus ID for device not given by udev. Trying to determine it from kernel name (2-3) ... Use top device d...

Finally EnableLogging =1 didn't solve the problem, unless there is some other setting to change.
However, the issue here is not about switching usb storage/mode but that the system detects/ recognises a wrong zte model.

This is the content of the file usb_modeswitch I will change to value EnableLogging=1 # Configuration for the usb_modeswitch package, a mode switching tool for # USB devices providing multiple states or modes # # Evaluated by the wrapper script /usr/sbin/usb_modeswitch_dispatcher # # To enable an op...

Ok, now opened the file with : leafpad /etc/usb_modeswitch.conf

I 'll see what i can do and come back here
Thank you
