My laptop has only USB 2.0 port. Can I convert my LAN port as a USB 3.0 port ?

If USB to LAN available ? Why not LAN to USB ???

Arent there any converters in the market that can do this ?? My aim is to upgrade my laptop from USB 2.0 to USB 3.0 using my existing LAN or HDMI Port.

Cant even a HDMI to USB 3.0 Not possible ??? I dont have Expresscard or PCMCIA slot in my laptop !!!

1) There are NO converters available.
2) They carry different forms of data that cannot be converted into the other.

Because Ethernet data can be encapsulated in USB. USB has all sorts of types of data, which cannot be addressed correctly without great trouble.

Just buy a USB hub and be done with it.

No can do.

If your laptop has an Expresscard or PCMCIA slot, you might be able to use that. However, in most cases you can't upgrade laptops.

Well, that's not happening.

The only way you're getting USB 3.0 on your laptop is via an ExpressCard add-on (if you even have an ExpressCard slot) or buying a new laptop.

As you said there are no current converters available.. But it is entirely possible to do this.. Rather its simple to, if you have the means to and the skills needed to code.

Doesn't exist either. You're out of luck.

I would like to see someone try to write the code and build the hardware at the other end... most of the addressing stuff in Ethernet controllers is done in hardware.

HDMI has the same issue. It's also solely an output with the exception of a very small amount of EDID info.

Despite what you have been told so far (ignoring the irrelevance of the posts about USB hubs!), USB via an ethernet port is possible both in theory and in practice. Here is one such device: http://www.digi.com/products/usb/anywhereusb

However, what is not possible is USB 3 speeds over ethernet. USB 3 data transfer rates are considerably higher than what can be handled by normal ethernet adapters.

Well, this is what happens after trying to study for board exams and trying to skim topics to answer.

That's USB 1.1 (O_O), 100Mb/s ethernet, and is a full-blown rackmount device rather than just an adapter. You'll need serious drivers that won't be included with Windows, too.

USB is like a "data bus" that can encapsulate other types of device's data, which includes encapsulating a network card inside of USB. A network card only understands networks and does not understand the kind of things a "data bus" needs to understand.

A strange analogy is your Internet connection can carry Netflix, but Netflix can't carry your Internet connection.

I'm afraid that is completely wrong. A USB bus transmits and receives data; an ethernet card transmits and receives data. A network card just encodes and decodes that information in a particular format, but the information can be whatever you like. The difference is just in the protocols, and physical media, that they use. It is perfectly possible to package USB data inside ethernet packets, as I have demonstrated by referencing a device that does just that.

How well that encapsulation is done is down to the speed limitations of the medium and the sophistication of the drivers that translate the data. In practice this means that only USB 1 is possible, and there is little point in supporting storage devices (for example) as USB 1 speeds are just too slow. But note that this is a practical limitation - or compromise if you like - not a theoretical one. With fast enough ethernet, and enough demand, you could make any USB device work with such a system.

Main thing is processing power, at a guess. All the stuff normally done in hardware generally has to be done in software for that kind of thing.

And latency - USB tends to be pretty sensitive.

Cant even a 1Gbps to USB 3.0 will do ?

USB 3 transfer rate is 4.8 Gbps. You never reach the maximum theoretical data rate with ethernet (particularly if there is more than one device on the network) and then there is the not inconsiderable overhead of encapsulating the USB data in ethernet packets. I doubt that even a 10Gbps fibre network could support USB 3 speeds even with the network just dedicated to that purpose.

It would be cheaper just to buy a new laptop.

Ok, i get your point. Thank you very much for all your info.
