Yes, that's normal in several cases. That's because the chip will only allow the specific firmware it came with and that's what you need to patch for the Bus Activation. If using a different firmware other than the original one, you'll have such signal loss issues.

hey all, is it possible to have two cards with mixed firmware (one stock and one flashed for mac)? That way, I could still have thunderbolt/usb3 in windows as well? Thanks.

Oh, yeah. That's possible. Although, have never experimented but it could be a nice idea and hopefully, it should all work well.
