where did you got the ethtool for the onion omega?
I cant find a package or binary.

Was someone able to activate the Auto-negotiation?
In the datasheet of the MT7620 it says that its possible to activate this.

Can I access this registers from the Onion or do I need to recompile the FW?

I found a solution with EthTool but this tool is not in the onion packages , so I cant test it.

for short distances ( within a PCB ) capacitive coupling is possible. See AN120
For longer distances Magnetics is recommended.

Hi :),
would it possible to use the LAN9500A (USB to Ethernet Chip) and connect it directly to the TX+/- and RX +/- of the Omega2+ Pins?

http://www.microchip.com/DevelopmentTools/ProductDetails.aspx?PartNO=EVB-LAN9500A-LC

On the Omega2+ is running a Webserver.
I like to connect the Omeag2+ to any Computer via USB and then connect trough my Webbrowser to the Omegas Webserver.

Because there is no USB OTG Client on the Omega. I like to know if this would be possible with a USB 2 Ethernet IC.

And also I hope I can connect it without transformers:
