The MediaTek MT7927 (Filogic 380) combo WiFi 7 + BT 5.4 module uses
hardware variant 0x6639 for its Bluetooth subsystem. Without this patch,
the chip fails with "Unsupported hardware variant (00006639)" or hangs
during firmware download.
Three changes are needed to support MT6639:
1. CHIPID workaround: On some boards the BT USB MMIO register reads
0x0000 for dev_id, causing the driver to skip the 0x6639 init path.
Force dev_id to 0x6639 only when the USB VID/PID matches a known
MT6639 device, avoiding misdetection if a future chip also reads
zero. This follows the WiFi-side pattern that uses PCI device IDs
to scope the same workaround.
2. Firmware naming: MT6639 uses firmware version prefix "2_1" instead of
"1_1" used by MT7925 and other variants. The firmware path is
mediatek/mt7927/BT_RAM_CODE_MT6639_2_1_hdr.bin, using the mt7927
directory to match the WiFi firmware convention. The filename will
likely change to use MT7927 once MediaTek submits a dedicated
Linux firmware binary.
3. Section filtering: The MT6639 firmware binary contains 9 sections, but
only sections with (dlmodecrctype & 0xff) == 0x01 are Bluetooth-related.
Sending the remaining WiFi/other sections causes an irreversible BT
subsystem hang requiring a full power cycle. This matches the Windows
driver behavior observed via USB captures.
Also add 0x6639 to the reset register (CONNV3) and firmware setup switch
cases alongside the existing 0x7925 handling.

Some MT6639 Bluetooth USB interfaces (e.g. IMC Networks 13d3:3588 on
ASUS ROG STRIX X870E-E and ProArt X870E-Creator boards) expose only a
single alternate setting (alt 0) on the ISO interface. The driver
unconditionally requests alt setting 1, which fails with EINVAL on
these devices, causing a ~20 second initialization delay and no LE
audio support.
Check the number of available alternate settings before selecting one.
If only alt 0 exists, use it; otherwise request alt 1 as before.

Add USB device ID 13d3:3588 (IMC Networks/Azurewave) for the MediaTek
MT7927 (Filogic 380) Bluetooth interface found on the ASUS ROG STRIX
X870E-E GAMING WIFI and ASUS ProArt X870E-Creator WiFi motherboards.
Note: boards with this USB ID report only one ISO alternate setting
(alt 0), causing a non-fatal "setting interface failed (22)" during
setup. Bluetooth still functions but initialization takes ~19 seconds
instead of ~2.6 seconds.
The information in /sys/kernel/debug/usb/devices about the Bluetooth
device is listed as the below.

First one is more concerning since it may mean it can lead to crashes
with SDIO driver, the other comment may actually need to be addressed
separately, perhaps WBS handling needs to be fixed on this family of
controllers.
