Below are the kernel logs for when I connect the USB on F42 (new kernel)

new(the one that doesn't work)

One thing I notice is the new upgrade trying to use ModemManager rather than NetworkManager. The device is also defined as “Mobile Broadband”, instead of “Ethernet”.

Loading the kernel module with modprobe, as another commenter suggested, didn’t make any change.

Another thing: An excerpt from the kernel changelog at https://cdn.kernel.org/pub/linux/kernel/v6.x/

rndis_host: Flag RNDIS modems as WWAN devices

[ Upstream commit 67d1a8956d2d62fe6b4c13ebabb57806098511d8 ]

Set FLAG_WWAN instead of FLAG_ETHERNET for RNDIS interfaces on Mobile
Broadband Modems, as opposed to regular Ethernet adapters.

Otherwise NetworkManager gets confused, misjudges the device type,
and wouldn't know it should connect a modem to get the device to work.
What would be the result depends on ModemManager version -- older
ModemManager would end up disconnecting a device after an unsuccessful
probe attempt (if it connected without needing to unlock a SIM), while
a newer one might spawn a separate PPP connection over a tty interface
instead, resulting in a general confusion and no end of chaos.

The only way to get this work reliably is to fix the device type
and have good enough version ModemManager (or equivalent).

I am so lost xD

This did nothing. I don’t notice any change at all

Seems to be rndis for me.

This really makes me wonder if free will even exists… I mean, 90% of what we do and what we think depends on environmental stimuli, the remaining 10% depends on genetic makeup and the natural variations/mutations of our brain cells.

That ability to make a choice is itself a result of being in the right time+place and receiving the correct guidance+education.

Like someone who read your comment might look into this and slowly learn to be more resilient, but if that same person doesn’t read it, never receives any guidance and has to suffer psychological abuse from those around them, would you really blame them for being the way they are?
