Description hjzach 2025-04-16 01:47:38 UTC

1. Please describe the problem:

Usb-tethering using the Fairphone 5 on a fresh install of F42 kde amd64 works out of the box. After updating the system it stops working.
Tried using a Samsung A13 5G, and usb-tethering continues to work after updating.


2. What is the Version-Release number of the kernel:

Fairphone 5 usb-tethering works: Kernel Version:  6.14.0-63.fc42.x86_64 (64-bit)
Fairphone 5 usb-tethering broken: Kernel Version: 6.14.2-300.fc42.x86_64 (64-bit)
Fairphone 5 usb-tethering broken: Kernel Version: 6.15.0-0.rc1.20250411git900241a5cc15.19.fc43.x86_64


4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Install Fedora 42 Kde amd64, then update.


5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

Yes.


6. Are you running any modules that not shipped with directly Fedora's kernel?:

No.

Reproducible: Always

When using kernel version 6.14.0-63, my device is identified as enp12s0f4u2.
Using kernel version 6.14.2-300, my device is identified as wwp12s0f4u2.

Other people in the 'Ask Fedora' forum, who have the same problem as I have,
have linked the behaviour to the following kernel patch: https://github.com/torvalds/linux/commit/67d1a8956d2d62fe6b4c13ebabb57806098511d8

Comment 2 hjzach 2025-05-15 07:09:31 UTC

Problem is solved after updating to kernel version 6.14.6-300
