Update in previous version: To inform the users about SD UHS-II cards, let's extend the print at card insertion with a "UHS-II" substring. Within this change, it seems reasonable to convert from using "ultra high speed" into "UHS-I speed", for the UHS-I type, as it should makes it more clear. Note that, the new print for UHS-II cards doesn't include the actual selected speed mode. Instead, this is going to be added from subsequent change.
