          Hello Geetha,

           

          Mass storage implementation will associate the device with a Microsoft defined class of USB devices (Mass storage class). This would help reduce the complexity as the Microsoft drivers and the default mass storage Windows applications can be used to communicate with the device.

           

          Vendor implementation needs the use of custom drivers and host applications. This is suitable in situations where the implementation does not pertain to a Microsoft standard class of USB devices.

           

          Best regards,

          Srinath S

              Hi,

               

              As Srinath already mentioned, mass storage devices makes use of MS Windows Drivers so it will take less time to implement. You can also make use of default mass storage Windows applications to read. If you go with vendor device class it would be time taking. So my suggestion is to go with Mass storage Class.

               

              Thanks & Regards
