Hello Surfplays,
Yes you can, but you would have to use the Vista USB drivers since there are no Windows 7 drivers for it.
Support and Downloads for Current and Discontinued products
If you are able to, you should use a ethernet connection from the modem to the LAN (ethernet) port on the back of your computer. This way you will not need a driver installed for the modem, and you will get better throughput.
Hope this helps,
Shawn
