I assume it's related to the wifi chipset, which is:

 c3:00.0 Network controller: MEDIATEK Corp. Device 7925

 mt7925e 0000:c3:00.0: ASIC revision: 79250000
 mt7925e 0000:c3:00.0: HW/SW Version: 0x8a108a10, Build Time: 
20231227093012a
 mt7925e 0000:c3:00.0: WM Firmware Version: ____000000, Build Time: 
20231227093232

I manually added it to btusb.c in 6.11.0-rc2 as below and it works fine 
with both my mouse and Bluetooth headset.  I'm just not sure where to 
place it in the list, I'll leave that to the maintainers.

{ USB_DEVICE(0x13d3, 0x3608), .driver_info = BTUSB_MEDIATEK |
                                             BTUSB_WIDEBAND_SPEECH |
                                             BTUSB_VALID_LE_STATES },

Thanks,
