I realy duno how u can connect to a ip adress without actualy asking for it to connect , the system is made to use a pc lihe a host and connect peripherials to pc , not to whatewer u want to connect it .
How will comunicate ur usb peripherials , if u dont start software ?
With who will comunicate ur usb dongles?
U can connect a train to a plane and ask them to go in some direction , but they dont comply.
For connecting a usb to work with a ethernet u need a gate and the device to comunicate thro that gate .
If u have skills in protocol comunications , then probaly u would acuire some thinks , but u need protocols from uc300 to mach3 or uccnc software , and u need to interfere this protocols .
