No meaningful changes to USB core or xhci_hcd, wild guess that maybe you could try reverting this? d34963d968a6 rndis_host: Flag RNDIS modems as WWAN devices I have the exact same issue with : - Phone : Fairphone 4 5G - Kernel: 6.14.2 - OS: Gentoo/Linux I just reverted that patch, and it works: d34963d968a6 rndis_host: Flag RNDIS modems as WWAN devices. I revert the 67d1a8956d2d on main (6.15-rc1*) and it fixed. thanks I have now also posted this to the mailing lists: https://lore.kernel.org/all/e0df2d85-1296-4317-b717-bd757e3ab928@heusel.eu/ |
