With Fedora 34 I am unable to use an external usb wifi card.
In specific from dmesg I see:

I also tried to download and build the Ralink RT3070 driver provided by the maker from MediaTek | RT3070 | Inexpensive Wi-Fi Devices but I was unable to get it working. Here the output after unzipping the download file.
