USB host-to-host communications.

Is it possible to have two PCs talking together over
USB? How is the connector ( same class connector )
handled. Doesn't the class A, class B connector
differentiate between host and device? Any input is
welcome.

Thanks in advance,

USB only allows a host to client communication model. However, there are
several third party cables that allow end to end communication, that is A to
A connections. These cables have a bulge in the middle containing hardware
that can emulate a device to each end of the cable.

 

Ideally and how it this done in pracice.

 

I expect this to be RNDIS-compliant Ethernet hardware. I have such a cable
lying around - can try if you want.

You go down to CompUSA, or whatever local computer strore you have nearby,
buy one of the aforementioned cables, reverse engineer the endpoints and
write a USB driver for each end. It really isn't difficult at all. So what
is the question exactly??

 

If I ask you what is the best HDD available on the market today will you
forward me to a store? Are there any ideal models that could serve as an
ethalon of functionality HDD should provide? Maxim Shatskih answered the
question, may be you have to add something.

 

I guess I don't understand the question.

There are several commercially available USB cables which allow end to end
communication. They generally come with their own drivers which setup some
virtual NIC on each end so you can use these like a network connection
between two PCs. If you need your own driver to control the cable, then it
usually isn't too hard to reverse engineer the USB endpoints for the cable.
You can choose to create your own virtual NICs for the thing, or just use a
straight USB WDM driver with a custom interface. Laplink is one brand I
have used before (http://www.laplink.com/products/cables/overview.asp purple
cable in middle). I was able to make my own driver for this cable in short
order.

RNDIS support is news to me, I never checked or cared.
