Hey Chris, of course.
I plugged in the USB Dongle CSR 4.0, attempted to scan my BT device,
unfortunately my usb device was not recognized. I also wanted to use
Wireshark with this dongle, but it was not detected as well.
I am able to use this device on Ubuntu 18.04 and scan my BT devices.
here is a description of
