No /dev/ttyUSB* or /dev/ttyACM* device after loading GobiSerial kernel module for HP un2430

[sinamomken]

Hello
I have an HP EliteBook 8470p notebook with an HP un2430 3G mobile broadband card, very similar to the setup @casastorta had in Aug 2012.
I tried a lot to make this mobile-broadband card work, but unfortunately in Kubuntu 16.04 it doesn't work unless I boot into Windows with Sierra drivers installed and then reboot back to Kubuntu; This process loads the Gobi 3000 firmware uploaded into the card in windows.

After searching a lot I got introduced with GobiNet and GobiSerial modules from Qualcomm and learned that I should install GobiSerial to become able to load the card's firmware using /dev/ttyUSB*.

Therefore, I cloned this repo, copied it into /usr/src/GobiSerial-2011-07-29-1026/, built and installed it using dkms, blacklisted qcserial and other "cdc" drivers and rebooted.
However, after the reboot, the "GobiSerial" driver don't create the /dev/ttyUSB* devices yet!

Below is output of ls /dev

What should I do to make "GobiSerial" detect my HP un2430 card and show it as /dev/ttyUSB*???

[ivuk]

Hi, I'm guessing neither me nor @casastorta have that hardware anymore. :)

For starters, you could try manually loading the module with the debug option, something like:

sudo rmmod GobiSerial
sudo modprobe -v GobiSerial debug=1

or

sudo modprobe -v GobiSerial debug=y

And pasting the dmesg output, that hopefully will contain some debugging information. :)

[sinamomken]

Here are the last lines of dmesg after reloading GobiSerial with debug=1:

[28021.367016] usbserial: USB Serial deregistering driver GobiSerial
[28021.367075] usbcore: deregistering interface driver Gobi
[28033.111265] usbcore: registered new interface driver Gobi
[28033.111299] usbserial: USB Serial support registered for GobiSerial
[28033.111309] GobiSerial: 2011-07-29-1026

This card (HP un2430) is important for me because it is one of the few mobile-broadband cards supported by BIOS of my 2012 HP laptop; And I don't want to replace this laptop yet.

[KthProg]

Same issue for me. Using AirCard 340U, and same result after running those commands. Using the version that supposedly supports the 340U didn't fix anything.

[vahid-dan]

@sinamomken @KthProg I have the same problem. Any solution?

[KthProg]

@vahid-dan Nope. We switched to a different modem with better documentation that actually works.
