I can test the patches. However, they do not apply on my NXP 4.19.96 kernel.
The only difference between v4.19.105 and my NXP4.19.96 kernel is that we are lacking
this commit:

USB: cdc-acm: fix unthrottle races
However, the 0002-cdc-acm-introduce-a-cool-down.patch you sent me seem to be based on
a newer kernel tree. It seems to depend on at least this commit which was introduced in v5.x:
commit 0f02321e4bd1b17eb957e077e868ef1611f5dbbd

USB: cdc-acm: clean up throttle handling
Please advice on how to proceed to make sure I test the code you intend.
