But why would I care? If somebody suspends synchronously, then that's what he wants.

Sure. But that sounds like a "Doctor, it hurts when I do this" situation. Don't do that.
Make the USB host controller do its suspend asynchronously. We don't suspend PCI bridges anyway, iirc (but I didn't actually check). And at worst, we can make the PCI _bridges_ know about async suspends, and solve it that way - without actually making any normal PCI drivers do it.
