there is a signal ground (black wire), and shield (bare). a good cable should have both. a cheap cable has the red, green, white and bare, relying on the shield to also function as the signal ground.
all the colors (black, red, white, green) will be the same in any cable bearing the USB logo (assuming its not a forged logo)

which contains all sorts of data, including the male/female connectors and what color corresponds to what pin.
the shield wire is intended to be connected to the shielded portion of the connector (the metal shroud around the contacts)
I don't think the USB spec accepts soldering usb wires directly to a circuit board, some type of wire to board connector must be used. In the case of a one-off project, it shouldn't make much difference. just solder the shield wire to the same place you solder the black wire.
y cant i just solder the wires directly to the board?
and if i cant than what other options do i have?
can i buy the connector (the square ones) both male and female from radio shack?
The USB specifications say a lot of things that people regularly ignore, and many of them only really matter if you want to get your device certified so you can stick a USB logo on it. for a hobbyist, it's not going to matter - adding an additional connector would not improve anything vs. a soldered connection, if anything it would be worse.

Why is this so complicated? a soldered connection is going to be better than using a connector. It's pretty simple, and I don't even see why you would have to ask if a soldered connection would work - of course it will, why wouldn't it?? It's nothing but a simple electrical connection of 4 wires.
I don't intend to sound mean, but seriously, you've already received answers, and it seems like you aren't even reading them!

What kind of question is that? Is there any reason that we should try to find out for you what you can or cannot buy at your local rat shack? If you want to know if they sell USB connectors, ASK THEM!
I'm almost afraid to ask what your project actually is...

no radio shack around this town for 1 i live in the middle of no where
for 2 could not find such a connector on there site
for 3

according to that or from what i am getting out of that im not supposed to solder a direct connection to the board or at least a MANUFACTURER that wants to keep the USB stamp of approval isent supposed to or somthing to that effect i was simply trying to clarify is all

a USB hard drive of mine got dropped off my desk and stopped being detected by my computer i took it apart and seen one of the pins from the actual connector on the board was broken was just going to simply solder the wires to where thay go no need to have a cocky reply or comment like that i am just trying to make shure i am understanding everything.
