Laplink USB 2.0 high-speed transfer Cable for use with all versions of laplink pcmover. What's so unique about laplink USB cables? Usb was designed as a pc-to-peripheral communication mechanism. Because of this design, it is not possible to plug a passive cable between the USB ports of two computers and transfer information. In fact, if you try this with an ordinary USB cable, you'll short the two power supplies together, possibly destroying one or both machines. Laplink cables include the necessary electronics to allow for the fastest peer-to-peer communication between the computers.
