Without a matching entry it only matches the generic USB Bluetooth class fallback, so the Realtek firmware/config (rtl8852btu_fw.bin / rtl8852btu_config.bin) is never loaded and the adapter cannot discover or connect to any device, even though hciconfig reports it as powered and scanning. Device descriptor: idVendor 0x1357 idProduct 0xc123 bcdDevice 0.00 iManufacturer 1 Realtek iProduct 2 Bluetooth Radio bDeviceClass 224 Wireless bDeviceSubClass 1 Radio Frequency bDeviceProtocol 1 Bluetooth Adding the same BTUSB_REALTEK | BTUSB_WIDEBAND_SPEECH quirk already used for 1358:c123 and 0bda:c123 fixes firmware loading and normal operation.
