Nada tadaaa!

When you unplug your bluetooth dongle, and plug it back in, it goes into a
"legacy mode" or "bios mode" or "usb compatibility mode" or "hid mode".
This is not good. The _hid_ mode has reduced bluetooth functionality. Your
mouse and keyboard will work (but only the standard buttons, not any fancy
multimedia buttons on your keyboard, and only 3 buttons on the mouse, not
any of the 9 other buttons). Any other bluetooth device, like a
smartphone, will not be able to connect.

To have full bluetooth functionality, your dongle needs to be in _hci_
mode. In hci mode, you have *all* buttons on keyboard and mouse, and you
will be able to connect with your smartphone.

When you issue the hid2hci command, you will notice that you are able to
connect your smartphone. However, when it asks you to enter a pin code on
the pc to verify the bluetooth connection, you will curse. Why? Because
with hid2hci, you have shut out your keyboard again...
