Perhaps this MCU request is not supported by old firmware from
linux-firmware repository.

Please download binary file accessible from this link
http://rt2x00.serialmonkey.com/pipermail/users_rt2x00.serialmonkey.com/2013-January/005610.html
and replace rt2870.bin file in /lib/firmware directory.

Does it help ?
