If anyone has any objections, please let me know. ------------------ From: Hrvoje Nuic [ Upstream commit ce21a5cf3d1fd92b84ea9ad2b7c7240aff2162d2 ] Add the USB ID for the Mercusys MA530 Bluetooth adapter. The device uses a Realtek RTL8761BUV controller and works with the existing Realtek setup path. The device reports vendor ID 0x2c4e and product ID 0x0115, and loads the rtl_bt/rtl8761bu_fw.bin firmware successfully with this quirk.
