USB tethering broken on Fedora 43

Hi all:
After upgrading from F42 to F43, when connecting my android phone and using USB tethering, the connection is seen as Ethernet, but not long after that it switches to WWAN and the connection is a hit or miss. I’ve researched about this and it was mentioned that it was fixed in kernel 6.14. I had no issues in F42.

A workaround that worked was to create a udev rule with the values of my device added to this "ATTRS{idVendor}==“xxxx”, ATTRS{idProduct}==“xxxx”, ENV{ID_MM_DEVICE_IGNORE}=“1"” and it seems to work again. Any ideas on how to properly fix this?

As a side note, I also reverted back to kernel 6.17.7 and a different version from f42 and still the issue was present.

I’m using usb tethering time to time and it works fine in all versions (fedora 42 rawhide KDE, fedora 43 kde).

also using wifi and LTE USB modem. It all works perfectly (much better than in windows 10).

your problem is not the kernel, it should be something else.
could you give more info on your phone etc?

Thank you for your reply. I’m currently using an old LG V30 with android 9. Wifi hotspot seems to work fine. I’m using fedora workstation with Gnome. I just booted a live usb with Fedora 42 and the usb tethering was working fine. Only on F43 with gnome the device switched from ethernet to wwan. Sorry I don’t have a KDE version to test it. The F42 usb had kernel 6.14.0.
