  • DUAL-INTERFACE FLASH DRIVE
    Publication number: 20140281139
    Abstract: Various embodiments relate to apparatuses and methods of dual-interface flash drives which prevent both interfaces of the dual-interface flash drive from being able to be simultaneously connected to interface ports of devices. This eliminates the risk of damage to or malfunction of the dual-interface flash drive as a result of both interfaces being simultaneously connected. As one example, a dual-interface flash drive can include a housing with a standard USB connector on one end and a micro USB connector on the opposite end. A flash memory is embedded within the housing, and a protective shield is attached to the housing.
