Hi Alex,

I am not very knowledgeable since I've only just started looking into adding
support for some older Realtek USB adapters, but another starting point for
adding rtl8822bu support might be the rtw88 driver, which is specifically
built for rtl88xx chips and which has support for rtl8822be (which uses PCIe);
in principle a lot of code can be shared between 8822b{e,u}. However, although
rtw88 includes some structure to support USB devices in the future, this support
hasn't been added yet. There is at least one project[0] that I've come across
trying to add that support. I'm not sure how active this project is but it does
look like they have some work in progress for rtl8822bu.

Best,
Geoffrey
