That's quite unfair. You make it seems as if we know virtually nothing at all. While many questions remain unanswered, lets not pretend as if we know nothing at all.
We know a lot of things. We know about brain chemistry, we know about neural networks,... we know quite some stuff from neurology etc.
So let's not pretend as if we are a bunch of drooling apes who don't even know what a brain is.
I talked about neurophysiology and neurotransmission and alluded to the importance of the ordering of the nervous system in my post. We know lots about the brain - I don't mean to imply otherwise. We don't have a theory of how the brain gives rise to experiences nor even a good guess as far as I can see.

Does it? It's not clear to me at all how you concluded that this gets us nowhere.
It seems to me that it gets us quite a long way already.
You just explained it. The "feels" is in the neurons firing away and activating pain receptors.
I don't think this explains it at all. What is it about neurons firing in patterns that implies feels?

No. You are excercising trust in a method of inquiry that has earned that trust with its immens and impressive track record of solving riddles that were once deemed unsolvable by many.
I am very confident in stating that IF one day we figure out consciousness, it will be figured out by a (or more) scientist(s) through science and not by some priest or monk or circus artist.
This is not "faith". This is trust based on an impressive track record of scientific success in doing exactly that: finding solutions to problems / answers to questions pertaining to nature.
Aye, I generally think along these lines myself. Science is an ever-growing box of tools and processes that we have adapted to fix so many problems and answer so many questions and on that basis I am confident that we'll get somewhere with this one. I do have a niggling feeling that this one is a bit special though.
Well, think of it like this. The pattern is *me smelling the coffee*. Whenever I smell coffee, that pattern (or one similar) occurs and whenever that pattern occurs, I smell coffee.
But is the pattern the smell of coffee?
I have to admit that I have never quite understood what the 'hard' part of the question of consciousness is. But, I also disagree with Chalmers about the coherency of p-zombies.
Saying something is physically identical to a conscious being but not conscious sounds like saying one system is physically identical to another but has a different temperature. It seems to me that both the temperature and the conscious state are determined by the physical situation, if known in detail.
But, I have to admit a similar difficulty understanding the meaning of the term 'qualia'. Does the quale of 'seeing red' also encompass the emotional response (in which case it is NOT indecomposable) or is it merely the sensation of the redness itself (in which case, what is the difference with sensory detection)?
I see this a lot. Some of us can't understand how some others can't see the problem and some others can't understand why we're having a problem to begin with. It might just be something to do with the ways we frame the world. That and words can be misleading slippery things.
Regarding that last paragraph, do you categorise seeing red as the same thing as sensing red?
What I mean is, I could train a machine to correctly identify red objects (in theory). Maybe it has a light detecting system and can just pick the object that reflects light in the right part of the spectrum. But it isn't 'seeing' red. There is no experience of redness or of anything else. Is this difference meaningful to you?
