Re: HP lt4220 (Snapdragon X12 LTE)

Turns out first log caused by regression in Linux 5.9 (I installed it to get fix for other issue). So it's not an usb-modeswitch bug. I will try to bisect it and will post result here, because this regression is directly related to usb-modeswitch and prevent it from working correctly. As for second ...

Re: HP lt4220 (Snapdragon X12 LTE)

Canonical dropped dispatcher-c-rewrite from their usbmodeswitch package: https://launchpad.net/ubuntu/+source/usb-modeswitch/2.6.0-2ubuntu1 So I moved on to Ubuntu 20.10 (and usbmodeswitch 2.6.1) to see if current usbmodeswitch will able to configure modem automatically. After all usbmodeswitch-data...

Re: HP lt4220 (Snapdragon X12 LTE)

I assume the line break in the path output was done by the pastebin webpage, right? No, line break came from this: #define OSRELEASE_FILE "/proc/sys/kernel/osrelease" which contain this: ~$ cat /proc/sys/kernel/osrelease 4.19.0-041900-generic ~$ cat /proc/sys/kernel/osrelease | hexdump 00...

Re: HP lt4220 (Snapdragon X12 LTE)

There is no "string" data type in C, but you don't need it as the actual string is already present: char* cdc_mbim_module_path; So you would need only the logging line, just where you placed it (after the "asprintf" line): Don't kill me if it doesn't work right away ... It works...

Re: HP lt4220 (Snapdragon X12 LTE)

Yes, there is "dispatcher-c-rewrite.patch" in that folder. That's the dispatcher of Ubuntu. If you want to help with finding the issue, see the function definition of "check_mbim_available". That's where the path for checking the availability of "cdc_mbim" is created. ...

Re: HP lt4220 (Snapdragon X12 LTE)

Just in case, here is source code of binary that I run: https://launchpad.net/ubuntu/+archive/primary/+sourcefiles/usb-modeswitch/2.5.2+repack0-2ubuntu1/usb-modeswitch_2.5.2+repack0.orig.tar.xz I don't think that this is what you are running. This is the original Debian source package which uses th...

Re: HP lt4220 (Snapdragon X12 LTE)

Obviously not removed in Ubuntu's homehacked version of usb_modeswitch.. They seem to have their own version of usb_modeswitch.tcl as well. Let them clean up their own bugs, I'm sure that the official usb_modeswitch will find the cdc_mbim driver and will select the mbim configuration, it has been p...

Re: HP lt4220 (Snapdragon X12 LTE)

The log you linked is somewhat strange. It shows that there is code in the wrapper to bind driver modules to the freshly mode-switched device. However, that code was removed entirely with version 2.4.0. Just in case, here is source code of binary that I run: https://launchpad.net/ubuntu/+archive/pr...

HP lt4220 (Snapdragon X12 LTE)

Hello! I trying to figure out how to get Snapdragon X12 LTE (labelled as HP lt4220) working with usb-modeswitch 2.5.2 on Ubuntu 18.10. Original modem state: https://paste.fedoraproject.org/paste/pHkIKctpSQm-iOMIqIGyeQ I tried to add /usr/share/usb_modeswitch/03f0:0857 with Configuration=0 and follow...
