Hello Xose,

sorry for double post - I accidentally pressed the wrong answer button :-(.

This is an expectation. The mentioned WUSB600Nv2 is one proof, that it
isn't (always) enough to successfully identify chips and derive, that it
behaves like other brands using the same chip. There have been brands
with this chip, which have been working fine (supposedly), but this
special brand didn't work at all here - even though it uses an already
known chip.

Chance :-)

rt2860 (PCI) chipset (rt2800pci) isn't experimental but is nevertheless
broken since 3.2 [1].

I'm seeing a fundamental problem (but not just here :-)) regarding QA. I
can't see any QA if there is done any change. Ok, I don't know all and
maybe, I'm blind, too. But I'm willing to learn .

That's why I'm wondering: When are all these appropriate devices going
to be tested? I think, a good point would be during development and not
after they have been released (means: "experimental" was removed). If
the ID's are committed, it should be ensured, that they really behave as
expected.


Kind regards,
Andreas
