On my netbook, the rt2870sta driver is the one supporting the 1737:0078 device. I'm not sure if this is because I added it, or not. My rt3070sta driver has no devices in the 1737 catagory. But that doesn't mean it isn't the correct driver.

You may need to try both. Just remember to remove the USB ID from the driver that you don't use. Otherwise you will have two drivers fighting for the wireless.
