Well the original Ralink driver does state this device is a 5GHz device.

RF3020 and RF3021 are 2.4GHz devices.

It could be that the initialization of RF3052 is incomplete, however that is not
limited to the 5GHz feature, but for both bands. Note that the
difference in initialization
only exists for settings the antenna and channel which already detect
if the initialization
should be done on the 2.4 or 5 GHz band.
So this argument shouldn't block this patch...
