No, you won't get the same device node back, AFAIK. At least not without reloading the scsi driver(s) if they were built as modules. After reinit of the USB controller holding a mounted storage device, the SCSI layer is convinced that the storage device is dead and won't let you do any operations on it. Take a look at udev. It is meant to solve such a problem.
