it should show under lsusb, but you must enable it when starting the image using "-usb":

and you may "plug" it in using qemu terminal (accessible through control+alt+2, control+alt+1 to switch back):
I tried it here and it worked, well, sort of... bt3 detected my usb dongle but airodump did not work (maybe my system did not released some resources of the usb dongle). I have not tried harder, since I have these tools already installed here but I think it may work.
ps: tried under linux, it should be almost the same under windows
