Description
MASS USB STORAGE DEVICE
FIELD OF THE INVENTION
The present invention relates to a USB storage device.
BACKGROUND OF THE INVENTION
A universal serial bus (USB) is a serial bus standard to interface devices.
The universal serial bus was designed to allow many peripherals to be connected using a single standardized interface socket and to improve the plug-and-play capabilities by allowing devices to be connected and disconnected without rebooting the computer (hot swapping).
One widespread use of USB is for USB mass storage device class. These devices have become extremely popular due to their small size and therefore portability. They are frequently used to carry around data.
Normally, when it is desired to remove a USB storage device from the computer, there is a requirement that the computer system close down the connection.
Failure to follow the proper procedure can result in loss of data.
SUMMARYOF THE INVENTION
It is an object of the present invention to provide a USB device which does not involve using the computer system and the user to shut down the device.
According to the present invention, there is provided a USB device which carries its own eject button on an external housing. Operation of the button will cause the USB device to notify the operating system of the attempt to remove the device.
BRIEF DESCRIPTION OF THE DRAWINGS
Having thus generally described the invention, reference will be made to the accompanying drawings illustrating an embodiment thereof, in which:
Figure 1 is a schematic view of a USB storage device according to the present invention;
DETAILED DESCRIPTION OF THE INVENTION
Referring to the drawing in greater detail and by reference characters thereto, there is illustrated in Figure 1 a USB mass storage device and which mass storage device is generally designated by reference numeral 12.
Mass storage device 12 may be of a conventional elongated rectangular configuration as is known in the art. Mass storage device 12 has a USB port 14 which is designed to engage with any suitable USB receptacle.
Mass storage device 12 includes a micro-controller 16 which is designed to interface, as shown by arrow 18, with a device (typically a computer) through USB port 14.
USB mass storage device 12 also includes a flash memory 20 which is in communication with micro-controller 16 as indicated by arrow 22.
The mass storage device 12 will include an eject button 24 which is in communication with micro-controller 16. Thus, micro-controller 16 can detect the state of eject button and will notify the computer system that the mass storage device is to be disconnected. Preferably, there is provided a light emitting diode 26 which will inform the user that the mass storage device can be securely removed.
It will be understood that the above described embodiment is for purposes of illustration only that changes and modifications may be made thereto without departing from the spirit and scope of the invention.
