Bluetooth won't install


Hope someone could shed some light why it won’t install?

I bough a Bluetooth CSR 4.0 last week and I am using an original pi b+ for this project for volumio 2.

I’ve tried installing the blue tooth dongle but I’ve followed several tutorials to no avail but I know the dongle works as I put it in my windows laptop and it worked with the drivers.

Ive done the debian update and upgrades and installed all the relevant applications/fixes etc and still the lusb command can’t see my dongle. I’ve also rebooted, took dongle out and reinserted.

Is volumio stopping this that I don’t know about ?

Thanks in advance
