You should be setting up your wireless in your router.
It is asking for a USB flash drive as it thinks that you want those settings
on other computers in your Network; and will save them to the USB for you to
taketo the others.
Conect your computer to the router with a Cat5 cable, log into the router,
and set the Network, and WPA2 security Key, up in there. Then turn on the
wireless in there!
Once you have done that, in Vista Start> connect to> put in Network name,
and security key that you made in the router.
