  • Continuously transferring data using a USB mass storage device
    Patent number: 9158645
    Abstract: A method for continuous data transfer when a USB mass storage device is disconnected and reconnected is provided. The method may include monitoring state information from one or more mass storage devices, using a software driver to detect a change in state of the mass storage device on the computer. Active I/O transfers using the USB mass storage device are paused when the software driver detects that the USB mass storage device is detached from the computer. A configurable timer is started. The software drive may detect the attaching of a USB device. If, prior to the expiration of the timer, the software driver verifies that the USB mass storage device is the same that was previously attached to the computer, active I/O transfers are continued.
    Type: Grant
