Package: linux-image-amd64 Version: 6.12.73+deb13-amd64 Severity: normal
The Mercusys MA530 Bluetooth USB adapter (VID:PID 2c4e:0115)
is based on a Realtek RTL8761BU chipset.
Adding:
{ USB_DEVICE(0x2c4e, 0x0115), .driver_info = BTUSB_REALTEK },
to drivers/bluetooth/btusb.c allows proper firmware loading
(rtl8761bu_fw.bin) and stable LE discovery.
Without this entry, discovery repeatedly toggles on/off.
Tested on Debian 13 (trixie), kernel 6.12.73+deb13-amd64.
