Considering how much time (man-hour) I spent trying to make my built-in Bluetooth adapter work on Linux, I decided it would be cheaper and faster to buy an USB adapter that actually works on Linux. So, I went out home with my laptop, tested an USB adapter and bought it. It is really small and cheap, it costed me R$ 30,00 (something between $9 and $10, according to today's exchange rates). It is able to transfer files and play music. Its package says Babbage Bluetooth Version 3.0 BM-BT01, it was made in China. On `lsusb`, it shows as `Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)`:

Pairing works on a trial and error basis, but once devices are paired, they work as expected. At least now I have a Bluetooth adapter that works on Linux. Anyways, I'm thankful for the time you spent trying to help me and giving me directions.
