u cant connect 2 pc's thru USB cable like normal ethernet cat5 RJ45 cable...
though u can opt for a USB hub....will allow u to connect more than 1 USB device....
its pretty much possible.chek out this link for more details.They specif`ically mention Laptop to Desktop Connectivity:

use a usb to usb cable available in your local computer store or baazee.com. the transfer is quite impressive if your comps use usb 2.0 but it works with usb 1.1 too
