I don't mention on upstream driver such as 'ukbd' (I think such device can be add truly dynamic),but I mention on 'host-controller' like [ou]hci. What I ask is what shall I do if there is a downstream driver without declared DRIVER_MODULE on upstream bus.Are there any way without changing upstream bus code?
