How to make a usb data cable for nokia e71 using old phone charger?

I want to make my own data cable for a nokia e71 using an old phone charger and a usb cable. The usb cable has 4 wires. Red (+ 5v), White (data +), Green (data -) and Black (ground). I am using a phone charger that fits in the phones usb port for the data cable. The charger only has 2 wires though (red and black). How do I wire this together to work correctly? I do not care if it charges my phone. I just want it to transfer data. Thanks in advanced.

Answer:

Okay, USB has four wires in each cable. Two of them are for data only. The other two are JUST power/voltage. It seems that the charger-only cable you got only bothered to include the voltage cables. In which case, the data cables are simply not there, and are not connected at all to the end that goes in your phone. I'm sorry, there's no way it'll work.
confident once you plug it into the desktops USB port it somewhat is going to attempt to load the drivers, which it could desire to wish the CD for. interior the destiny verify you plug it into the comparable USB port or it somewhat is going to attempt and reload the drivers every time you plug it right into a different port, in common terms considered one of those quirks abode windows has. additionally charging by way of the USB port takes a lot longer than in case you plugged it right into a mains charger.
