Is it simply to export an interface to hub_port_logical_disconnect()? What's wrong with using usb_reset_device()? You say it will "bring the device back to full reset state"; I'm not sure what that means. Do you want to avoid issuing a port reset? This patch won't help, because hub_port_locical_disconnect() will also cause a port reset. In fact, the USB stack can't reenumerate a device without resetting it.
