simple usb question

[pin9876]

Data +  and data -     which is data in and which is data out??thanks    usbA looking straight at the pins... and they always green and white???

The D+ and D- make a differential bidirectional signal, there is no in and out as such.
The cable colors are defined in the spec so should always be the same.
