I have good news and bad news for you.
1. Bad News - It does work, but you have to use ndiswrapper and ndisgtk to get it to work.
2. Good News - I didn't get into the detail, but someone claimed it worked under a different atheros module. They didn't specify the module. I have had to do this same thing before and what I did was find a recently manufactured atheros chipset that closely matched and used its module, and it actually worked.
With all this being said, you may need to read this post on this very forum:
Chipset is different than what you claim you have, but nothing new there, I have seen quite a few cards that had same model number and different chipsets. But it looks like updating the kernel in bt4 may help. Man, if you have already done that, get a different card I guess....Code:http://forums.remote-exploit.org/backtrack-4-non-working-hardware/27630-ralink-rt2870-issues-bt4pf-linksys-wusb600n.html
