Using a USB Bluetooth adaptor

[Phil]

Thank you for reading this.

I bought a Realtek Bluetooth adapter 5 because my ageing laptop does not 
support Bluetooth Low Energy. The adaptor's blue led is lit and it shows 
up as #2 in the Bluetooth manager but a scan doesn't discover any Low 
Energy devices.

It came with an installation disk for Windows so I tried the driver 
installation there to see what would happen but the installation was 
blocked by Windows because of an unauthorised Bluetooth adaptor error. I 
did, however, discover that the required driver is 8761B which is 
already installed in /lib/firmware/rtl_bt/.

I have Xubuntu version 22.10. I have Bluetooth adaptor #2 selected under 
"Bluetooth Adapters". Is there another step that I'm missing? An 
Internet search hasn't revealed any extra steps.
