Mini Subject: MESS
I recently aquired an old PC with no LAN built in, with the spare odds an sods lying around I managed to get it running wired from the usb, this was done in a very fuckabout kinda way:

(I'll try my best to explain this)A (is the pc) is connected to B (a modem/router with usb/LAN only capability and inactive dsl) via usb cable (would have connected it straight to the main modem/router but it doesn't have a usb socket, only wifi+4xLAN) then B is connected to C (24 way office router rack only there to replace the cross over cable that I don't have/couldn't be arsed chopping up one) and finally C is connected to D (the router with the wifi/LAN and operating dsl).
ip route
pc=192.168.0.51
B-router=192.168.0.50
D-router=192.168.0.1
B-router is behaving exactly like a pc as far as the D-router is concerned so the D-router is giving it access, the office rack (C)is just cross linking and has no I.P. to speak of, the B-router is bridging the LAN>usb (it also bitches about not finding internet via it's dsl line) and is not behaving as it was designed, B-router inadvertently gives the PC the internet.
P.S. I made this post on this mess
