Yeah it's unfortunate. Maybe the rise of these cheap knockoffs is what drove a company like Creative, who were one of the first to open their drivers in the mid 1990s, to their current position of not releasing any hardware specs or Linux drivers at all.
Well truth be told, not much has changed quality wise since then;) Ok I jest some, but I dont really find creative to be all that great anymore myself. Not even a big fan of the EMU line;)
But that has little to do with your point I suppose. I agree things like that above happening are quite unfortunate, though sometimes I wonder if there was a bit more to it than just that in their case.
IIRC Behringer is careful not to infringe patents - they just copy things that can't be copyrighted or patented like a circuit board layout. But I'm not really an expert.
Well considering they have already knowingly violated FCC regulation with some of their products, it would not surprise me in the least to see if they had violated patents as well, and most likely knowingly.
Can you tell I am not a big fan of them;) Seablade
