Greetings "ctops.legal" et. al...

I couldn't agree with Jerry more! Even if configured for data
transfer, USB is bandwidth limited for data of any substantial
size. This is why our networks have notoriously been Ethernet
based. The good thing about two computers that sport an Ethernet
connection is you don't require a hub or a switch if you merely
want to connect the two together.

In front of me right now is a Belkin package for a CAT5e
Crossover cable M/N: T3532G/A. Many other companies are making
the same type of cable - probably for less money. Connect this
cable between two computers having an Ethernet port and you'll
typically have 10 or 100MBit/sec. connection and something less
than that regarding the actual data transfer, considering the
overhead, but it will usually be more than adequate for PC use.
This is the way to establish data transfer at a better bandwidth
with a protocol that was established for broadband reliable data
transfer.


That's ok if both computers have an Ethernet port. If they don't, you
have to install a network card, and configure them to the same networks.
I have the software and active USB interface that installs and works in
minutes, without changing the network configuration. It has a USB power
processor that handles the data transfer, and handshaking. I have found
a cheap one that works OK at a 'Dollar Tree' store, for a dollar, plus
sales tax. I gave them to friends who wanted to borrow the expensive
one, and they worked fine.

http://www.usb.org/about/usb_nomenclature states that USB currently has
a maximum data rate of 480 Mb/s, or almost five times that of 100 Mb/s
Ethernet. Also, keep in mind that the actual data rates are about 20
MB/s and 40 MB/s

These are both burst rates, because no PC can maintain those data
rates on a continuous basis.

If you want to claim 'mentor' status, please give all the facts, not
just your personal preferences. If someone wants to copy an entire hard
drive, there are better ways, but to move some files between computers,
either works OK. In the shop, I use a USB wireless internet to install
software from the shop server, since there are places I haven't finished
the network cabling. I have the advantage of being able to set up a
computer anywhere there is enough space to work, without worrying about
finding a free ethernet port.

http://www.lyberty.com/tech/terms/usb.html has a comparison chart for
the common interfaces, and versions.
