If the device does not pass the above 2 checks it is _not_ a rt73usb device. And forcing the driver to work with the device will result in all kinds of problems. If rt2x00 is loaded and detected the device, it should print out a debug message that starts with: "Chipset detected - " What is in your case the complete line?
