Confirmed working on a device reporting as "MERCUSYS Bluetooth Adapter"
(USB ID 2c4e:0115, bcdDevice 2.00), retail product Mercusys MA550H.
Same RTL8761BU chipset, identical firmware load sequence.
Seems the USB ID 2c4e:0115 covers at least two distinct retail
products (MA530 and MA550H) from the same vendor.
