rt2800usb device will not operate in 11a/5Ghz mode

Description

I have an Alfa USB 802.11 adapter using the rt2800usb driver which I am trying to use.

The only reason I wanted to use it was for 5Ghz operation, but that doesn't seem to work. Setting "option hwmode '11a'" in my wireless config causes loading/starting to fail.

I have the proper firmware/drivers installed and it seems to work fine in 2.4Ghz/11g mode.

Notably, I get this error in logread:

daemon.notice netifd: radio2 (30357): command failed: Not supported (-122)

Take it upstream or is this an OpenWRT issue?

I am also experiencing the same issue on 15.05.1 with a similar Alfa card for the same purpose.

I also show Available Antennas: TX 0 RX 0

Forgot to mention, the adapter I am using is AWUS051NH - https://wikidevi.com/wiki/ALFA_Network_AWUS051NH
