Are you honestly trying to blame it on USB 3.1 vs 2.0 .You are not been realistic at all, you are been rather closed minded to what is currently going on. Wheel setups matter immensely, not everyone has the same devices. When it comes to wheel setups on PC, then you are very naive. When you think about all the different setups people can have on PC, the different parts people mix and match; the differing driver settings. Everyone has a different personal opinion on what the FFB should feel like as well, so we all use different settings. Giving the dev that is talking to us the relevant information will help more than I think you realise it will, it means that dev can input those settings on his end, it means he can use the wheel setups we have. If they do not have a particular wheel, well its a company owned by microsoft; so I would hope they would buy in the kit they needed to do the relevant testing with. On top of that you also have to contend with varying motherboards when it comes to PC, all with their own USB setups. So you have USB 2.0, USB 3.1 and USB 3.1, and unlike the xbox one; they are not set drivers across the board for it. There are so many variables when it comes to this stuff, that there is always something new to find out, to investigate, and to fix.
So as I asked you already, drop the chip you clearly have on your shoulders for the time being, provide some constructive information for the dev who is asking for it, give him the benefit of the doubt; be part of the solution and not part of the problem. Being abrasive over this isnt going to help anyone. If nothing changes, then fair enough; distrust T10 all you want. But for once we seem to have someone at T10 who does want to get to the bottom of this.
I have no grudges about anything, I just know how marketing these things works and am being realistic, if you are expecting a big change I can assure you, you will only be left disappointed. Given the resources T10 command the fact they can't get close to teams who have one guy doing all the physics and FFB is just embarrassing and I don't blame that on this guy, it is all on Greenawalt for not caring about important things like proper FFB.
