Those sorts of devices often have full-up driver stuff built into the
dongle, so the dongle itself does all the wireless stuff required
without bothering the system. Then, yes, they appear as USB devices
because that's all the dongle presents to the USB port. They're not
general-purpose BT dongles. My Logitech wireless keyboard/mouse does
precisely that. The wireless mouse shows up in "lsusb" as a USB-PS2
wireless mouse, but NOT as a BT mouse (because it isn't BT).

I have a Broadcom USB BT dongle. The BT dongle shows up in an "lsusb"
as a BT dongle.  Remember, Bluetooth means it uses RF in the correct
frequency bands and adheres to the Bluetooth protocols and that's all
it means.
