Subject: [PATCH] Bluetooth: btusb: Add support for 1357:c123 Realtek 8852BE device
Date: Wed,  8 Jul 2026 01:15:49 +0300	[thread overview]
Message-ID: <20260707221549.27269-1-playximik29@gmail.com> (raw)

Wiko Hi MateBook 14 Ryzen 200 laptops (DMI system-product-name
"MNCA-XX", board "M1060") are equipped with an RTL8852BE Wi-Fi/BT
combo chip (rtw89_8852be), whose Bluetooth radio enumerates as
1357:c123 instead of one of the already-supported 1358:c123 / 0bda:c123
identifiers, presumably due to OEM rebranding. 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.
