I have read the guide on building a XIM1 and I am just about ready to build my own for my PS3. I just have one question. How can I build the XIM1 without the need for a PS2 to PS3 adapter? I see a few XIM1 for PS3's being sold online that have a USB connection on both sides and do not need a PS2 to PS3 adapter. How are they able to do that? I have scanned through the forum and noticed a few other people asking the same question without a definitive answer.
