Driver Ugreen Bluetooth 53
Linux handles the UGreen 5.3 adapter with sublime elegance. The kernel module btusb (since Linux 5.15+) contains the quirk tables for Realtek/Actions chips. Upon insertion:
However, older kernels (before 5.18) may fail to load the firmware. In that case, the "driver" is actually a manual firmware update via fwupd or copying new .bin files. The community maintains these firmware blobs because Realtek does not open-source them – they are signed blobs executed by the chip's internal microcontroller.
