assuming windows: start -> run -> 'cmd' -> ipconfig /all [enter] All details will be shown, look for the hardware address of the particular usb connection
thanks for that RTT, but i was hoping to be able to find it without having to plug the modem into it. but i did anyway..lol cheers anyway
it doesn't have one unless there's a piece of networking hardware attached to it... the mac address you're actually finding is that of the modem, not of the USB plug USB plugs can sometimes have IRQs though
