Hello,
I'm searching for some help.. I'm not able to have my new wireless USB card working...
Unfortunatly I have no idea of some important things:
- wich commands can help me to check if my OS is seeing the card?
- what is the device driver?
- wich steps may I have to do for see the wireless interface connection?

Please help me to find a configuration mode / rules...
It should be also helpfull to have information about some documents explain the argument..
Thank YOU!!! CIAO, Paolo :-)

I went through the process if installing a Ralink RT73 USB dongle to a Dell Optiplex desktop runing CentOS 4.4 a short while ago.
I recorded what worked for me on my web-site: www.coulterfamily.org.uk (as an aide-memoire to myself if nothing else!).
Follow the PCs and Workstations link to Linux and then to Wireless.
Thereon is a step-by-step of what I found (eventually) worked for me and at the bottom of the page are a couple of tables with a number of links to drivers and information that I found useful, especially links such as:

Hope that helps.
