Add the vendor/product IDs (0x0b05, 0x1bef) and (0x0b05, 0x1d70) to the
usb_device_id table for the Realtek RTL8761CU-based ASUS USB-BT540 and
USB-BT600 adapters. Both bind 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 entries the driver loads
rtl_bt/rtl8761cu_fw.bin (already shipped by linux-firmware) and the
adapters work (tested: A2DP and ASHA).
Similar to commit bc597f0cc44f
("Bluetooth: btusb: Add TP-Link UB600 for Realtek 8761BUV").
Both adapters share the same descriptor layout and differ only in
idProduct, hence a single patch adding both entries.

I recommend to make it two patches. (The summary/title would also be
shorter then.)

Either way, this looks good.

Dear Paul,
thank you for reviewing.
As you recommended, the change is now split into one patch per adapter.
Patch 1 introduces the new "Realtek 8761CU" section (the header comment plus
the USB-BT540 entry), patch 2 adds the USB-BT600 entry to that section.
Changes in v2:
- Split the single patch into one patch per adapter, as recommended by
Paul Menzel.

Add the vendor/product ID (0x0b05, 0x1bef) to the usb_device_id table for
the Realtek RTL8761CU-based ASUS USB-BT540 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").

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").
