https://bugzilla.kernel.org/show_bug.cgi?id=60824 --- Comment #232 from Jack (ostroffjh@xxxxxxxxxxxxxxxxxxxxx) --- I guess it's just been too quiet here. I have one of those Chinese dongles that started working based on patches much earlier in this thread, and then without the patch with an earlier 5.1x kernel. It worked fine with all of the 5.19.x kernels I used, but it won't work with 6.0.0.
