[PATCH] Bluetooth: btusb: Add ID 0b05:1825 for ASUS QCA ROME adapter

[Edgard Lopes]

The Bluetooth radio of the ASUS combo WiFi/BT card based on QCA6174
(e.g. bundled with ASUS motherboards / PCE-AC55BT) is a QCA ROME
device rebranded under the ASUS vendor ID:

  idVendor=0x0b05, idProduct=0x1825, bcdDevice=0.01
  bDeviceClass=e0 Sub=01 Prot=01 (full speed, MxPS=64)
  Both interfaces Cls=e0(wlcon) Sub=01 Prot=01, driven by btusb

Without the quirk, btusb treats it as a generic adapter and never
loads the QCA rampatch firmware, leaving the device running its bare
ROM firmware. In that state SCO/eSCO audio is broken: the controller
delivers malformed packets which the kernel drops ("Bluetooth: hci0:
corrupted SCO packet"), so HFP/HSP microphone input never works, and
the kernel also logs "unexpected event for opcode 0x2005" during LE
operations.

With this entry the device is set up as QCA ROME:

  Bluetooth: hci0: using rampatch file: qca/rampatch_usb_00000302.bin
  Bluetooth: hci0: QCA: patch rome 0x302 build 0x3e8, firmware rome
0x302 build 0x111
  Bluetooth: hci0: using NVM file: qca/nvm_usb_00000302.bin

after which eSCO audio works in both directions with zero errors
(verified with HFP against JBL Live 770NC and other headsets).

The driver_info flags match the sibling QCA6174 entry 0cf3:e300.
