@lucydev Those cheap WiFi 6 dongles on AliExpress? Quite a few of them have chips that are either partially supported (Bluetooth only) or unsupported in the kernel. If you get a few different <$5 ones you're likely to have at least some that don't work OOTB.
@lucydev Oh, alternatively some older scanners, I believe some of the CanoScan devices still don't work under Linux (not sure if that's a kernel driver thing though?) and they're usually everywhere on classifieds sites
