Actually - it *does* help. This would explain why the driver doesn't
work, and tells me that the rt2860 issue is indeed known about. My
frustration stemmed from my constant fighting with the official ralink
driver, and the fact that I was unable to obtain a response from either
them or this project on why my rt2860 cards couldn't talk to the world.

The tech support address I dug up on their site doesn't appear to be
particularly responsive to requests for help with their official driver,

That describes the issue I've been seeing perfectly. MCU error,
scanning works, association fails.

I have managed to get the official driver to work with WPA/WPA2 after
several months of fighting with it. Perhaps it's time to take the last
released version of rt2860sta (220.127.116.11, iirc) apart to see why it can
wake the hardware up? Unfortunately, my perl knowledge is much better
than my C, but if I can help in any way, I'll be happy to do so. If I
have to deal with the official ralink driver for much longer, I think
I'm going to toss these cards. :P
One of my ralink cards is a spare, and I have a test environment
consisting of spare hardware and netbooted installations set up. While
I can't promise I'd be quick due to a lack of free time, I *can* compile
kernels and drivers. If there's anything you'd like me to try, please
let me know.

No worries, Luis - your English was perfectly clear, and quite helpful.
