(this will not help you, sorry, but I had to write it anyway)

Since we started the rt2800pci driver a while ago, we did follow all
of the init procedures of the legacy driver, and thouroughly checked
and rechecked all steps.

But in my case, ALL of my rt2860 based adapters fail with the MCU
request error, and we haven't found yet a reason for it.

I've asked Ralink for help with this issue, but so far, no solution
has been provided in order to fix it.

It seems that right after loading up the firmware to the device, it
accepts it with NO errors at all, but the MCU isn't getting waked up
or otherwise started.

This is the error, "MCU request failed".

Apparently, this error does not stop the card from receiving probe
requests and somehow, the RX paths seems to be partially working.

But none of my cards associate at all.

So, in a nutshell, (I) we have no clue on how to fix it, but are
completely open for suggestions.

p.s. please forgive me for any incorrections in this text, English is
not my native language.
