A USB dongle can be generic BT, works with any BT mouse, headset, keyboard.
OR
A USB dongle can be proprietary 27 MHz, 49 MHz or 2.4GHz, and usually only works with device it came with (joypad, mouse, keyboard). May not be encrypted. In theory the 315 / 430 approx (USA vs elsewhere), or Euro 864 MHz (USA maybe 915 MHz?) can be used, but I've not seen mice use those.
However sometimes BT isn't secure either.
