While I've not tried btscanner, yet, on bt4 pre-final, my gut instinct would be that your bluetooth device is not recognized by the kernel when you're running btscanner (driver might not be loaded, etc.)  A couple of things to look for:

1.) try turning the bluetooth switch / adapter on before bt4 ever boots, to make sure the OS sees it and tries to initialize it (assuming the proper device drivers are present)

2.) look up the make / model of the bluetooth adapter, and see if it's supported on Linux, and if there are linux device drivers for it.

You could also send us the output from a terminal window, and issuing the lspci command, to see what bt4 sees.  You can 'pipe' it to a file, using:

lspci > ~/Desktop/devices.txt

Then copy / paste the output or contents of the file to this list, if you want some of us to see if your hardware is compatible, etc.

this is the output although i turned on the bluetooth key be4 booting
