Mr. schasch.
Here comes a hell 'o nooby question...

Do I have to install any app before the mentioned process?
I mean... I tried the ifup usb0

and "-sh: ifup: no found"

I would preciate some help, though I mean not to offend you (For I feel the nooby nature of this, for the asnwer might border on obviousness)

Ty on advance
