Message-ID: <bug-216336-208809@https.bugzilla.kernel.org/> (raw)
https://bugzilla.kernel.org/show_bug.cgi?id=216336
Bug ID: 216336
Summary: 3G USB Modem Huawei k4203 stop working on kernel > 4.X
Product: Drivers
Version: 2.5
Kernel Version: 5.18.13
Hardware: Intel
OS: Linux
Tree: Mainline
Status: NEW
Severity: high
Priority: P1
Component: USB
Assignee: drivers_usb@kernel-bugs.kernel.org
Reporter: socratesdevel@protonmail.com
Regression: No
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:
