I think you probably can't get those messages without creating a window, so
try creating a window before getting events.
Also, you don't want to have a separate poll and wait func, which are both
called and both check for different messages. Both those functions remove
messages from the queue, so if a your poll function gets a SDL_KEYDOWN
message, it would end up throwing out the message and then your wait
function would never receive it. Just do the Poll thing, and make it's
switch statement do the prints for SDL_KEYDOWN as well.
Anyways, once your test program works for your normal keyboard, then you can
try it out with the wireless in order to learn how SDL is or is not reading
that things key data, which will help you understand where the problem lies
and how to solve it.
