There are no longer individual drivers.

Instead there is one shared source code and two device drivers:

- rt2860 covering RT2860 and RT3090 devices

- rt2870 covering RT2870 and RT3070 devices

In comparison rt2800usb currently lacks RT3070 support and rt2800pci's
RT3090 support is basic at best (not to mention that it didn't work for
RT2860 last time that I tried)..

I bet they are truly grateful for being shown "the one and only way"..

I was able to use my Eee 901 successfully with them for a last year and I'm
pretty sure that I'm not the only.  I understand my sin now -- I should have
had help in fixing the proper and clean code before using my hardware.. [*]

Well, it would be much more productive if people concentrate on improving
_their_ projects and looking at downsides of _their_ code instead of going
around and looking at _obvious_ downsides of other people's projects.

[*] [Slightly off-topic but it shows the same problem with the approach]

I now also see why some distributions keep pushing some known non-working
things on their users (Fedora maintainers -- I'm talking to you), the best
example is PulseAudio -- it simply doesn't work reliably even on modern
hardware and/or using all scheduler tricks (it seems that making Linux into
full RT OS is a prerequisite for fixing latency issues observed)..

So yeah desktop/laptop/mobile users, do not worry -- you will get your sound
support back in few years time and if you're developer: don't dare to complain
you fussy saboteur!!
