As most modern computers no longer have an Ethernet port, it would be great if future devices would be an Ethernet adapter for any laptop powering them. So if you power the device throug the mini-USB port this would also turn them into an ethernet adapter.
Made one device like this and it is ready for production. But the software side is not finished so we need some more time to test before we could release it.
I know this is an old thread, but I’m looking for exactly this as well.
Was the product being developed the USB150?
Is there a product more like a travel router with a host USB port that also accepts power via its micro-USB port but transfers data on the micro USB port as well. The micro USB port on the router would function as a device port (or OTG) supporting the CDCether protocol.
