With the device ID in the table, the adapter is handed over to btrtl, which in this tree, together with the backport of commit 4a23ce935f74 ("Bluetooth: btrtl: Add the support for RTL8761CUV"), now requires rtl_bt/rtl8761cu_fw.bin. That file is only shipped by linux-firmware since 20251111. On systems with older firmware packages, such as Debian trixie, the adapter no longer initializes. Without the ID entry it binds via the generic Bluetooth class and works on its ROM firmware, as it did before the backport. Mainline keeps the ID entry, so this revert is for 6.18.y only, as agreed in the regression thread.
