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.
