no output at all…

That means there were no errors. Did you check for any changes in your modems status.

Please post the input/outputs of all requested commands via the terminal as text, (not as pics).

How to provide good information in your posts

When asking questions in the forum, it would be most helpful to all members if you provide some basic information. When you provide info from the terminal, usually from your logs, you have to format it so the content is easy to read. First copy and paste your text/terminal/code into the post Then select the text/code and click the post edit toolbar button </> . Another handy way is to use 3 backticks ` at the start and 3 more at the end of the text like this: ``` Paste text or code here …

Please format any terminal output with three backticks before and after, as shown in this picture:

[kubwit]

unfortunately no change. it seems to be recognized and connected to ttyXXX but no way to configure connection from GUI . i didnt try to configure it from with nmcli and to connect manually.

no sign of life XD

[tbg]

Just checking, did you install “usb_modeswitch” because it seems to be required from any of the threads regarding this adapter I’ve read.

[jonathon]

Before we go too far with this, the adapter works correctly in another Manjaro installation on another system. This means the issue is more likely to be related to the laptop rather than Manjaro.

For example, certain USB hardware doesn’t work properly in certain USB3 ports.

The other option is that you have somehow altered the configuration (e.g. through udev rules) which are preventing normal operation.

Also

did you install “usb_modeswitch”

[tbg]

sudo rmmod dell_laptop

That was my thought as well, thats why I had him rmmod the pesky manufacturers module that causes so many problems with wifi. Unfortunately it had no effect.

[kubwit]

did you install “usb_modeswitch”

sorry for creating confusion. this was referred on another system. the tests we did today are on fresh install and live usb stick

For example, certain USB hardware doesn’t work properly in certain USB3 ports.

right. the inspiron 6400 is quite old and it is also an old usb stick.

The other option is that you have somehow altered the configuration (e.g. through udev rules) which are preventing normal operation.

i altered anything on this laptop. only installed the moden manager gui in xfce. the fact there is the same issue on gnome live usb shows that there is no altered settings.

what makes it weird to me is that it seems to be fine from cli. in xfce i can also add the connection with its parameters but there appears no option to connect…

[tbg]

From the lsmod you posted earlier it appeared that your modem was still in storage mode, which is detected as a cd drive of all things. You must use usb_modeswitch to change it from storage mode to the modem mode.

From the ArchWiki:

Mode switching

Often these devices will have two modes (1) USB flash memory storage (2) USB Modem. The first mode, sometimes known as ZeroCD, is often used to deliver an internet communications program for another operating system and is generally of no interest to Linux users. Additionally some have a slot into which the user can insert an additional flash memory card.

A useful utility for switching these devices into modem mode is usb_modeswitch, available in the official repositories.

Udev rules are supplied with the package in /lib/udev/rules.d/40-usb_modeswitch.rules . This contains entries for many devices, which it will switch to modem mode upon insertion.

When a device is switched, its product ID may change to a different value. The vendor ID will remain unchanged. This can be seen in the output of lsusb .

Some devices are supported in the USB serial kernel module called “option” (after the Option devices, but not limited to just those) and may be used without usb_modeswitch.

Udev itself included a utility called /lib/udev/modem-modeswitch . In udev 157 this was renamed to /lib/udev/mobile-action-modeswitch and morphed into a tool that only switches Mobile Action cables. For other devices use usb_modeswitch .

https://wiki.archlinux.org/index.php/USB_3G_Modem#Mode_switching

[kubwit]

You must use usb_modeswitch to change it from storage mode to the modem mode.

that was one of the issues. The gnome machine where it works has the entry and the modifications i posted initally on this thread.
i pasted the

i tried to add to /lib/udev/rules.d/40-usb_modeswitch.rules

# Huawei E220, E230, E270, E870
ATTR{idVendor}=="12d1", ATTR{idProduct}=="1003", RUN+="usb_modeswitch '%b/%k'"

in and restarted. now i have the device visible but not working.

i have the broadband connection configured but it does not connect.

any more idea?

the lines in /lib/udev/rules.d/40-usb_modeswitch.rules

# Generic entry for most Huawei devices, excluding Android phones

is there a reason that there is a “S” in “ATTR” ? the other lines all have “ATTR” and not “ATTRS”

[tbg]

Mine is the same way Here are all the Huawei device entries in my:

/lib/udev/rules.d/40-usb_modeswitch.rules

# Generic entry for most Huawei devices, excluding Android phones
ATTRS{idVendor}=="12d1", ATTRS{manufacturer}!="Android", ATTR{bInterfaceNumber}=="00", ATTR{bInterfaceClass}=="08", RUN+="usb_modeswitch '%b/%k'"

# Huawei ME909u-521 (MBIM, dummy config)
ATTR{idVendor}=="12d1", ATTR{idProduct}=="1573", RUN+="usb_modeswitch '/%k'"

# Huawei ME906, ME909 (MBIM, dummy config)
ATTR{idVendor}=="12d1", ATTR{idProduct}=="15c1", RUN+="usb_modeswitch '/%k'"

You may want to check that your vendor ID and your product ID match at least one of the entries in those lines.

I have never owned a 3G modem, so this is all pretty much guesswork on my part.

@bogdancovaciu is far more familiar with udev rules than me. Perhaps he can advise if it would be a good idea to create a rule for your model containing your specific ATTR{idVendor}== & ATTR{idProduct}==.

[tbg]

Looks like @bogdancovaciu is enjoying a well deserved break, perhaps @AgentS can comment on the udev rule. Do you think he has to add his device ID’s into a custom entry.

[AgentS]

can comment on the udev rule. Do you think he has to add his device ID’s into a custom entry.

Thanks for the guessing challenge! I am not experienced on udev rules, except I try to understand the RTFM… , so I had to review the topic history…
Being on hit-and-miss road, adding a specific device entry would not hurt (more…).

One question:
Are we talking about a Manjaro system or Archlinux? (it shows a Manjaro kernel, but I had to ask…).

By experience, some times Device IDs change, or there are some strange situations that a different ID than that in lsusb works.
Maybe OP should review dmesg in detail, on the relevant dmesg parts, and also post again lsusb or other info to verify how the HW is recognized.

I hope I could say more., It seems I need to play with systemd services AND udev rules on next year, apart from my book authoring…

[tbg]

Udev rules are a weak point for me as well. I’ve just never had much cause for writing custom udev rules. The only one who really seems on top of his udev stuff is Bogdan (at least that I’ve noticed).

Anyways, thanks for responding, I’m sure your input was helpful as always @AgentS .

[bogdancovaciu]

ATTR{idVendor}==“12d1”, ATTR{idProduct}==“1003”

Bus 001 Device 002: ID 12d1:1003 Huawei Technologies

This seem ok, but then on the latest post about the 40-usb_modeswitch.rules it seems to be

ATTRS{idVendor}==“12d1”, ATTRS{manufacturer}!=“Android”

No, i’m not much into this rules, and modems are quite unknown to me.
This should work tho, by adding also the InterfaceClass:

ATTR{idVendor}=="12d1", ATTR{idProduct}=="1003", ATTR{bInterfaceClass}=="08", RUN+="usb_modeswitch '%k'"

After reboot and while trying to connect it should ask for the PIN number.

[AgentS]

Without RTFM I suspect

• ATTR= one specific target
  while
• ATTRS= multiple matching targets
