Seems to requires a non-free firmware (as of 2011-02-20). Firmware download is officially for RT28XX/RT30XX series, but the RT3077 and RT3370 share the same driver, so I'm assuming the RT3370 has a similarly restricted firmware.
In addition, reports module license as 'unspecified' to kernel, causing kernel taint.
Tested with unbranded USB dongle:
