I seem to remember that the problem with USB was that you can't even know how many things are still outstanding; devices are free to appear on the bus at any time after bus power on, without specified timeout... If the kernel can't know what's out there, it can't wait until it has a complete picture either, just by virtue of not being able to know when that is achieved ;-) But I could be wrong entirely; USB storage is not something I delve into daily...
