You CANNOT connect 2 computers together with a normal USB cable. You 
need a special cable with an electronic circuit known as a USB 
laplink cable such as *www.cablesnmor.com/usb-laplink.html
If you use a normal cable you can short ur USB ports
even tho this isnt require but yet
	
	
		
		
			You can also connect using a crossover cable between the parallel ports 
and the serial ports of two computers but the NIC cards and RJ45 
crossover cable is probably the simplest and least expenisve way to go.
		
		
	 
now u usually get software with some cables .. to set ur usb port as a network adapter ...
or u can use the windows direct cable connection .. try it out !
