So they sell pairs of USB - Cat5e/6 adapters that allow you to extend USB devices over ethernet.   I've seen them for USB 1.1 and 2 but not many for 3.0

 

I happen to have USB to Ethernet adapters lying around that allow you to use a usb port for networking.      These parts look like the same thing.  The only difference is that it comes with a female type A on one of the two dongles where both of mine are male.   I was wondering if I get a USB gender change for one of them if it would work, or is there some sort circuitry inside that allows the dongles that I have to only be used for ethernet and could not convert back to usb???

To try and simplify what I am asking:

There is a product sold as usb over ethernet which simply consists of two dongles, one has a male type a usb connector and a female rj45 connector, the other is the same except that type a is female so that a usb device on the other end of the ethernet cabling can be plugged in

 

In this setup, if you took a usb to ethernet dongle that is sold with the purpose of a wired network connection through usb, can it be substituted in the scenario above   ?

I expect that you have got no answer so far because nobody actually knows - particularly as you have not supplied any specific hardware information.

 

I would also expect that the units you have are powered by their USB connection - so only the one at the computer end of the cable would be powered if you tried to use it as a USB extension.

 

If I wanted to know the answer to this question & I already had most of the parts lying around then I would just try it & find out for myself.

This sounds like an experiment.  I'm not sure of the distance you'll get reliable connections.  Is this an attempt to run ethernet  over  in house phone lines or running ethernet over  USB cables??

Thanks for the replies.   I don't think it will work.  I just need a gender changer to try it which is why I havent.   People even complain about issues with the ones that are sold for the purpose I want.   I think there are chips inside that dictate the purpose of the adapter

key word you are looking for is a "Balun".  you want a usb to cat5 balun for extending usb lengths.

they make 2 types "passive" which is cheap but the distance is shorter or "active" which is amplified so you can run even longer distances.

 

you however cannot use a usb/ethernet adatper, that is an actual ethernet controller for plugging into a network and only works that one direction.

 

baluns are cheap and come in a set so you can extend the length, usually you get about a max of 100 meters (300ft) with a passive balun.

Thanks.   If I used a powered USB dock with hdmi port , do you think the video would work over the powered connection?

now that I know what your trying to do, it would be better to get hdmi to cat6e baluns to run a long distance.  you can use cat 5 with it, but 3d probably wont work with it. 

and you have to use 2 cat5 wires for hdmi to work.

then invest into a KVM switch!  instead of messing with extending usb.

KVM = keyboard video mouse
