So is it brand new? And if it is, do you have any clue on how it is
different, better?. It is
advertised as a T1R1 device, so I don't understand why they release
that works like the 3070...
Well, I'll see if I can invest some time on it...

Hi Gertjan, thanks a lot for the very fast reply, I appreciate it.
The device does not have any kind of brand on it, It came on a plastic container
with a green cover and a very generic instruction booklet. The mini CD that came
was burned (so no series production) and it contained the staging driver for the
5370 chipset (which is entirely useless for me as I won't use anything
other than rt2x00)
I guess it is some sort of generic OEM device, I'll see if I can get
some more samples.
