Could you please try not to type everything in bold? It only makes your posts harder to read, and it sure won't get you any speedier responses. It's like you're shouting, just one step below caps-lock.
The O2 neither supports displaying modern camera RAW files (not to mention every manufacturer specifies their RAW format differently than the next), nor does it have USB-OTG. Not sure where you got that info from.
I know Cowon's website mentions "unlimited RAW support", but the O2 of course does display neither the .CR2 RAWs from my Canon DSLR, nor the .ORF RAWs from my Olympus.
