Compilation ok.
loading (insmod) ok.

But when you access the /dev/zzyUSB0 device the task hangs. CTRL-C does not cancel the task. Reboot only.

Does not work on Manjaro (Kernel 5.10.51) either.
What works is to take the official kernel (5.10.64) from kernel.org and compile the ch341 module yourself.

There is a fantastic guide on how to do that:
https://wiki.archlinux.org/title/Compile_kernel_module

win11 is the same
