Innovative Approach of USB Communication

The popularity of Universal Serial Bus (USB) storage devices is an indication of the computer user's need for a fast, large capacity and easily accessible system for data storage. The disadvantage of USB storage devices is that being a peripheral device, it needs a host, usually a Personal Computer (PC) to initiate and mediate communications between two USB storage devices. The USB slave to slave file transfer system seeks to create a bridge between two slave devices for file transfer when a computer is not available. The USB Slave -to-Slave File Transfer System (USS FiTraDev) utilizes USB controller to facilitate file transfers while smartphone is used as user interface. As we know almost 90 % peoples have smartphone because of its low cost but problem is that we cant exchange the data from one USB to another USB by using smartphone so to overcome this problem we have create this USS FitraDev device. We use smartphone as user interface and gives operation command from smartphone via Bluetooth. For communication between USB controller and smartphone we use Bluetooth module as mediator. We can copy single file, single folder or entire memory content from one USB to another USB. The system allows overwriting when a file of the same name is found in the destination flash drive. If the destinations USB don?t have sufficient memory space then it indicate the message ?insufficient space? on smartphone display. Device uses two ?A? sized alkaline batteries & also operate on AC supply. (by using adapter)
