Dear Gustavo,
Thank you for your patch. Just a note to add all listed MAINTAINERS
entries to the receivers (`scripts/get_maintainer.pl
drivers/bluetooth/btusb.c`).

It’s common to add the output of `/sys/kernel/debug/usb/devices` to the
commit message, cf `git log drivers/bluetooth/btusb.c`.

The IMC Networks MT7922 Bluetooth adapter with USB ID 13d3:3625 is not
recognized as a MediaTek device because it is missing from the btusb
device ID table. As a result, btmtk firmware loading is never triggered
and the HCI reset command times out with -ETIMEDOUT.
Add the device with BTUSB_MEDIATEK | BTUSB_WIDEBAND_SPEECH flags,
consistent with the neighboring 13d3:3627, 13d3:3628 and 13d3:3630
entries which use the same chip.
Tested on: MediaTek MT7922 (Wi-Fi 6E combo card, IMC Networks BT USB
interface), kernel 7.0.11-arch1-1.
