Okay, I finally understand what the original problem was. usbfs won't let you do a set-configuration call if any of the interfaces in the current config is already bound to a driver. That's why your attempt failed. Yes, if the correct configuration is already set then you can skip the call entirely. That's the easiest solution. Things become a little more difficult if you really do need to change the configuration. You would have to unbind the interfaces in the current config first. It's a nuisance but it's doable.
