I get various errors when I try to connect the LYLYGO T-Keyboard to my FreeBSD system using different BT dongles

I would like to connect the LYLYGO T-Keyboard to my FreeBSD system (14.2) using a BT dongle. To be honest I tried two different kind of dongle,these ones : a) ugen1.6: at usbus1 ubt0 on uhub0 ubt0: on usbus1 and this one : b) ugen1.6: at usbus1 ubt0 on uhub0 ubt0: on usbus1 but both failed to establish the connection between the BT dongles and the keyboard. This is how I have configured FreeBSD : /etc/rc.conf bluetooth_enable="YES" blued_enable="YES" hcsecd_enable="YES" /boot/loader.conf netgraph_load="YES" vkbd_load="YES" ng_ubt_load="YES" net.bluetooth.usb_isoc_enable="0" Then,I turn on the T-Keyboard and I see the message : Wait Bluetooth. On the FreeBSD terminal,I do : marietto# hccontrol -n ubt0hci create_connection E4:B1:63:01:52:0A but I get these errors : Status: Page timeout [0x4] ugen1.6: at usbus1 ubt0 on uhub0 ubt0: on usbus1 ng_l2cap_lp_receive: ubt0l2cap - unexpected ACL data packet. Connection does not exist, con_handle=12 Limiting closed port RST response from 239 to 205 packets/sec ubt0: ubt_bulk_read_callback:1131: bulk-in transfer failed: USB_ERR_IOERROR ubt0: ubt_intr_read_callback:1032: interrupt transfer failed: USB_ERR_IOERROR ugen1.6: at usbus1 (disconnected) I have no idea how to make it work.
