HI i finally decided to make a USB programme AVR USBasp and leave my serial programme behind. i am following this https://rabiuls.wordpress.com/2011/08/06/atmel-avr-programmer-usbasp-modifiedsimplified-pcb/ and made the pcb, drilled it and soldered all the parts except the usb, for USB i am using a old camera USB cable. Now i am a bit confused, in the pcb there are four holes for USB connection, out of the four which 2 are 5v+- and data +- . My cable red and black is power and green white is data.
