Hi Sascha

glad you found some *working* devices for rtw88 !

I spend some of the weekend testing your driver submission.

for rtl8821cu devices I get following output

some Logilink device

above is same with some from Comfast

The worst in the list is one from EDUP

[ 1818.171505] rtw_8821cu 1-5.1.2:1.2: failed to setup chip information

rtl8822bu devices are working fine ...
