Well for starters it would help if you could give a somewhat more concise
Aside of the aforementioned Ralink and Zydas (which USB works easily with
Linux and doesn't even seem to need a firmware blob ).

"For some things we do require non-disclosure agreements, but we are generally
able to provide the API documentation and the firmware driver interface
specifications for our hardware. As to why others may not be able to do
this... well, our software is developed in-house, but others might out
outsource their driver development to third-party companies, so they may not
even have the documentation that a programmer requests.
We usually provide driver source code, and we try to put it under the GPL if
possible, so that's usually good enough if you want to write your own driver.
If you want to see more than that, we generally require an NDA, or if you're
an embedded customer, we provide reference platforms." Some of the Atmel
drivers are even in 2.6.20 as is Zydas.
Realtek and RAlink have similar statements of wanting to work with Linux
vendors. And that investigation was done by someone who didnt actually want
to buy anything.
Realteks USB chips require 3.3V and 1.8V, 5V is "tolerated" for input.
they don't seem to support SPI. Realtek seems to think they are fit for use in
phones and lists mobile phone as application area explicitely. Publically
available data doesn't seem to list power consumption. Driver tarball on the
site seems to consist of sources only.
 I once looked at the driver tarball and didn't find it, in any case. It
might still be hidden inside some variable deepdown in a source file.
