From dc16388d45ecbd3be0d8c9424dbbaa2c81806578 Mon Sep 17 00:00:00 2001 From: Tibor Harcsa Date: Mon, 29 Jun 2026 22:34:20 +0200 Subject: Bluetooth: btusb: Add IMC Networks QCA9377 to quirks table Add the USB ID (13d3:3503) for the IMC Networks Qualcomm Atheros QCA9377 Bluetooth controller to the btusb quirks table. This device requires Qualcomm Rome firmware and wideband speech support to function properly; otherwise, BLE scanning fails with HCI unexpected event opcode 0x2005 errors. The device reports the following in /sys/kernel/debug/usb/devices: P: Vendor=13d3 ProdID=3503 Rev= 0.01 C:* #Ifs= 2 Cfg#= 1 Atr=e0 MxPwr=100mA I:* If#= 0 Alt= 0 #EPs= 3 Cls=e0(wlcon) Sub=01 Prot=01 Driver=btusb E: Ad=81(I) Atr=03(Int.)
