Working on a project and I need to find out how the computer and USB actually work together. What is between the USB port and the circuit board? How does the computer actually receive/send the info.? mainly I'm looking for pictures, diagrams, drawings....something to show the relation ship between the two.

try that link out... if you need more technical get back to me... ie if you need an example of how data is passed and how the motherboard interprets data between the original usb "appendage"

Cool...Thanks...
