Phoenix Network Forums

I wonder if it is possible to connect 2 PCs via their USB ports to create LAN network. Theoritical speed for USB 2.0 is 480mbit/s and it is much faster than 100mbit LAN card.
There are USB bridge cables like this one:

With such cable it is possible but the question is:
Is it possible to make something like USB crossover cable like crossover UTP LAN cables ?

It is possible, and people have done it (and do it I would assume) however, off the top of my head I couldn't think how you would easily acomplish it.
I someone remember there being a stupid bottleneck in the system though which is why its not something you see commonly.

It is possible.Check http://www.shoeboxcomputers.com/product_info.php?products_id=771
I don't know other information.For more check google.

If I were you, I would look into making a network with 1394 or firewire. It's speed is 400mbps and from windows xp's perspective, it already looks like a network connection which would make it alot easier to configure. I myself use this setup for high speed file transfer between my main desktop and my laptop.

I believe the bottleneck which you are refering to is the data transfer rates of today's hard drives. USB is supposed to have a data rate of around 400 MBPS, problem is that EIDE's top speed is around 150 and SATA just came out with the SATA 300 drive which goes at, you guessed it, 300 megs sustained data transfer rate. So, with those rates, what is the point of using USB or firewire to transfer data? It really isn't even worth it to use gigabit networking in a home or small business capacity because of the hdds again. The only situation I can think of where such High speed networking would be a plus is in data centres or large enterprises where they can actually aford to put in scsi 480 drives in all their server boxes. In conclusion, you can use USB or other highspeed networking at home, but the performance increases will be neglidgable at best and not worth the time and effort you would have to invest in getting everything up and working.
