asus usb bt400 bluetooth usb adapter cd install

My problem is not the last error (since that is only a matter of installing the proper driver) but instead, the running Linux image does not recognize the adapter as a Bluetooth device.

Bluetooth: hci0: BCM: Patch brcm/BCM20702A1-0b05-17cb.hcd not found bluetooth hci0: Direct firmware load for brcm/BCM20702A1-0b05-17cb.hcd failed with error -2 usb 2-1.6: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 2-1.6: New USB device found, idVendor=0b05, idProduct=17cb However, the expected output would be something like the following, which I found on the proper USB-BT400 GitHub installation guide: usb 2-1.6: new full-speed USB device number 6 using ehci-pci usb 1-1: config 1 interface 1 altsetting 0 endpoint 0x3 has wMaxPacketSize 0, skipping usb 1-1: config 1 interface 1 altsetting 0 endpoint 0x83 has wMaxPacketSize 0, skipping

When I plug the USB-BT400 adapter, the output of the dmesg command is the following: usb 1-1: new full-speed USB device number 2 using ci_hdrc I need the Bluetooth connection to receive some data stream to be furtherly processed on the board. Image v2.6 (I cannot use the latest because the FINN framework installation is not compatible with it).
