What is the best way to connect and transfer USB over 2 free ethernet pairs?

Question

USB

It is required to transmit a normal ethernet signal over 2 pairs over a single 4-pair ethernet cable (up to 100 Mbps), and use the remaining two pairs to passively extend USB. In theory, for ethernet, I will leave the orange and green wires. And what is the best way to connect plus, ground and two USB pins? Power on one pair (which one is more correct?), And data on the other, or power / date +, and earth / data -? In principle, the solution is only for me, but maybe there are already some established standards?

Answer 1

but it doesn’t bother you that there will be pickups + the hertz difference will jam each other, and they don’t do that. IMHO

Answer 2

As long as they don't bother. Ignorance is power.
That is, I still do not know whether I should be afraid or still try. That's why I'm asking...
