If anyone has any objections, please let me know. ------------------ From: Christoph Zwerschke commit 6f0624b4427e38c3bb63a951c536cf8adaee1238 upstream. Add the vendor/product ID (0x0b05, 0x1d70) to the usb_device_id table for the Realtek RTL8761CU-based ASUS USB-BT600 adapter. It binds via the generic Bluetooth class today, so BTUSB_REALTEK is never set and the rtl8761cu firmware is not loaded, leaving the controller non-functional. With the entry the driver loads rtl_bt/rtl8761cu_fw.bin (already shipped by linux-firmware) and the adapter works (tested: A2DP and ASHA). Similar to commit bc597f0cc44f ("Bluetooth: btusb: Add TP-Link UB600 for Realtek 8761BUV").
