Hi! Mistakenly I bought this adapter (UGREEN bluetooth 5.4 adapter). Looks like it is not supported under Linux: https://forums.opensuse.org/t/bluetooth-5-4-usb-stick-connected-on-a-desktop-computer-with-opensuse-15-5-with-kde-not-working/173916/31 However I see that windows uses stock drivers for this device. What do you think is needed to make this adapter work in Linux? I didn't notice windows downloading firmware for it, since it just started to work out of box. Best regards, Maxim Levitsky
