Hi,
Respeaker core v2 only show internal Bluetooth adapter when a USB Bluetooth dongle is plugged.

lsusb command shows the USB dongle as 'Sennheiser Communications'.

respeaker@v2:~$ lsusb
Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 006 Device 002: ID 1395:002d Sennheiser Communications
Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

However, hciconfig only shows the internal Bluetooth.

respeaker@v2:~$ hciconfig
hci0: Type: Primary Bus: UART
BD Address: 44:2C:05:84:7F:6E ACL MTU: 1021:8 SCO MTU: 64:1
DOWN
RX bytes:654 acl:0 sco:0 events:33 errors:0
TX bytes:419 acl:0 sco:0 commands:33 errors:0

How can I do for recognizing the USB Bluetooth dongle?

Best regards,
