Description S.Bonomar 2022-08-08 05:28:54 UTC
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.

My log on fedora-36:
