I do not know how rt73usb words, but it is possible that the device has
firmware generating Beacon frames and it would only use a Beacon frame
from mac80211 as a template for configure the firmware to do the rest.

hostapd does not send beacons, it just configured mac80211 with a
template and beacon interval.
