October 21, 2025Oct 21 Yeah so just like the title says, has anyone got a tip for a USB Bluetooth dongle that works with the mainline kernel? I got a UGREEN Bluetooth 5.0 dongle a while ago and have just tried again, installing firmware for it. It does get detected as a USB device and the firmware loads. But bluetoothctl never finds it. Gnome doesn't let me 'enable' bluetooth. I'd like to avoid buying a string of these so was just wondering if any are working with mainline? Cheers!
