When I saw the usb hub I was shocked at how advanced it would be. I thought he'd just throw down a high speed at best simple thing. Not a board with frankly a lot of high speed serial and protocol conversion. I'm not surprised it didn't work but I don't know this person's background enough to fully know if that's the expected outcome.
I love mechanical keyboards, but not enough to carry the weight of one in a laptop. The engineering is still very cool.
I just want everyone to make arrow keys regular-sized and not Apple-sized.
