Devices with Ralink RT2770F Chipset that use the RT2800 driver can successfully be used with the aircrack-ng suite combined with compat-wireless. This forum posting provides an excellent description of how to install the compat-wireless software. This provides the rt2800usb driver.
This driver may successfully be used with other devices that require rt2x00 drivers. Please post success/failures to the forum.
