“Recognized” is bit a big word. What you see is that the codes 0bda:b812 are found in a list on your system. That list has as many as possible names of vendors and products, so that lsusb (or other tools) can provide you with that, easier to read, information:
Vendor: RealtekSemiconductor Corp.
Product: USB3.0 802.11ac 1200M Adapter
But that is only explanatory text. It does not mean that there is any software on board to do something useful with it.
