urtw(4) has no firmware, run(4) has the appropriate depend line. The
rt2870 driver is not in-tree, contact the maintainter.

You should by now have noticed that you can't use a Realtek driver with
a Ralink chipset, or the other way around. So please stop calling both
broken in one mail. Also, again, the rt2870 driver isn't in-tree,
contact the maintainer.
