Usb Hooking Code I Am Looking For A Computer Program That Will Run Diagnostics On Another Computer Through Usb Port?

I am looking for a computer program that will run diagnostics on another computer through usb port? - usb hooking code

I want a program that will be on a laptop that is diagnosed with another computer via the USB connection to your laptop is loaded. Free is good, but are willing to pay for the program. Something like a computer, a vehicle and the error code, get in touch again to say what is wrong with him. Help to access such a program would be welcomed thank you in advance.
