Does the same USB cable work and get the phone charging if you use it with the adapter power plug/socket? Might be something wrong with the cable. Have you tried just plugging it into another PC or Mac to see if it registers?

Your mac won't read DFU mode properly unless you update to 10.5.7 first.
