Subject: [PATCH v2] Bluetooth: btusb: Add IMC Networks QCA9377 to quirks table
Date: Mon, 29 Jun 2026 22:34:20 +0200	[thread overview]
Message-ID: <20260629203420.24137-1-silurust@gmail.com> (raw)
In-Reply-To: <20260627153505.20173-1-silurust@gmail.com>

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:
