i am new on kernel development, i can successfully use my Huawei vodafone k4203 usb modem with kernel version 4.15(I test it on ubuntu-18.04.1 LTS with kernel 4.15 (i donwlaod this iso on 2018)) but when i try to use it with the newer 5.x.x kernel i get the error "kernel: cdc_mbim 2-1.5:2.0: SET_NTB_FORMAT failed kernel: cdc_mbim 2-1.5:2.0: bind() failure" when I want to use I enter on ubuntu-18.04.1LTS, insert the device and reboot and enter on fedora-36 but when I enter the fedora-36 and insert the device, reboot and enter the ubuntu-18.04.1 LTS, the device fails on ubuntu-18.04.1 LTS, just remove and insert again and it works Now i'm use (Fedora_36 kernel 5.18.13-200.x86_64) I compiled the kernel-{5.4,4.19} longterm and the problem persist But when I access the 4.x.x kernel then reboot the PC and access the 5.x.x kernel it works, do you have any idea how I can solve this problem ? :) Note: the modem has a dhcp server and web server.
