Here is the info from both commands plus lshw -C network......without the Ralink usb installed, since that is not the wifi interface we are trying to find.....
kenneth@kenneth-ME051:~$ lsusb | grep Ralink
kenneth@kenneth-ME051:~$
kenneth@kenneth-ME051:~$ iwconfig
lo no wireless extensions.
eth0 no wireless extensions.
kenneth@kenneth-ME051:~$ lshw -C network
