From: Alexander Hall <bearodark@xxxxxxxxx> This patch fixes bluetooth support on the MediaTek MT7925 WiFi 7 + BT 5.3 M.2 chipset that I purchased from aliexpress (and which arrived today). The PCB states that it is an MT7925B22M. I tested that this patch did fix my problem; bluetooth now works. The chipset was purchased from here, though the storefront image does not match the PCB that was recieved: https://www.aliexpress.com/item/3256806821207897.html Signed-off-by: Alexander Hall <bearodark@xxxxxxxxx> --- This is my first submitted patch to the linux kernel, apologies if I have misunderstood any portion of the process. drivers/bluetooth/btusb.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/bluetooth/btusb.c b/drivers/bluetooth/btusb.c index e384ef6ff..2ea46a0e6 100644 --- a/drivers/bluetooth/btusb.c +++ b/drivers/bluetooth/btusb.c @@ -691,6 +691,9 @@ static const struct usb_device_id quirks_table[] = { { USB_DEVICE(0x13d3, 0x3603), .driver_info = BTUSB_MEDIATEK | BTUSB_WIDEBAND_SPEECH | BTUSB_VALID_LE_STATES }, + { USB_DEVICE(0x13d3, 0x3604), .driver_info = BTUSB_MEDIATEK | + BTUSB_WIDEBAND_SPEECH | + BTUSB_VALID_LE_STATES }, /* Additional Realtek 8723AE Bluetooth devices */ { USB_DEVICE(0x0930, 0x021d), .driver_info = BTUSB_REALTEK }, -- 2.45.1
