Description Patrick Monnerat 2025-02-27 01:04:23 UTC
When starting a RPi 4 with the LTE Huawei dongle (12d1:1f01), the device stays in CDROM mode and is not switched to LTE router mode automatically.

/var/log/message shows "usb_modeswitch failed with exit code 1".

Manually submitting "usb_modeswitch -v 12d1 -p 1f01 -W -J -R -w 400" in a root session succeeds and performs the switch.

usb_modeswitch-2.6.1-11.fc41 worked like a charm and downgrading to it restores proper functioning.

Reproducible: Always

Steps to Reproduce:
1. Plug a Huawei LTE dongle.
2. Start the computer
3. Login to a root session
Actual Results:  
- The dongle LED stays red
- lsusb shows it as a mass storage device (CDROM icon on desktop).

Expected Results:  
- Led blinks red, then turns green,
- lsusb shows it with a different product id and as an LTE
- Networking starts on device.

ok , you already wrote the version, I will check

Comment 3 Patrick Monnerat 2025-02-27 01:12:33 UTC
> which version ?

usb_modeswitch-2.6.2-1.fc41

I set it in the BZ form, but it seems the latter does not show it on final page :-(

Comment 4 Sergio Basto 2025-02-27 01:30:07 UTC
please see https://bugzilla.redhat.com/show_bug.cgi?id=1373274 if not a similar issue

udev file moved from /usr/lib/udev/ to /usr/lib/udev/rules.d 


moreover 

 For debugging of the automated system integration, edit (as root or su) /etc/usb_modeswitch.conf in a text editor and change the line

 EnableLogging=0

to

 EnableLogging=1

This gives you a verbose output of the hotplug activity to /var/log/usb_modeswitch_<device>.

> udev file moved from /usr/lib/udev/ to /usr/lib/udev/rules.d

I'm currently relying on usb_modeswitch-data-20191128-12.fc41 which contains /usr/lib/udev/rules.d/40-usb_modeswitch.rules

Updating this file manually (for tests) shows changes are effective (/var/log/messages) but all attempts failed.

> EnableLogging=1

Thanks for the info and your investigations.

Comment 6 Sergio Basto 2025-02-27 12:59:29 UTC
ah ok , I going revert the move of usb_modeswitch to /usr/lib/udev/rules.d  , it was wrong 

Thank you for your bug report
