Abstract: A computer-based method and apparatus transfer files from a source media to a destination media. In one embodiment, the presence of a source media in a source storage drive is detected. In response to the detection, a user is prompted to transfer files from the source media. Then, in response to user input, files are transferred from the source media to the destination media. In another embodiment, a user is prompted for a transfer session identifier. Data is then transferred from a source media to a subdirectory on a destination media. The subdirectory corresponds to the transfer session identifier. The method and apparatus aid in migrating computer data from one storage technology to another (e.g., from media based on an older technology to media based on a newer technology).

Abstract: A method and system for enabling a computer application that executes in an environment in which support for USB does not exist (e.g., in the DOS environment) to interact with a USB storage device. In a most preferred embodiment, a system and method is disclosed for restoring a computer system from a storage device on a USB utilizing a disaster recovery application that executes in DOS.

Abstract: A method of guaranteeing a minimum sustained data transfer rate to a chosen device connected to a USB bus. A set of filter drivers are inserted in the driver stacks for at least two USB devices. These filter drivers are controlled by a filter driver controller that provides and receives information from the filter drivers. When a particular device needs a minimum sustained bandwidth for a transaction, the filter driver for that device notifies the filter driver controller. The filter driver controller then instructs the filter drivers for at least one other device to start interfering with USB transactions. This interference prevents the interfered with devices from using any of the USB bus bandwidth thereby providing a minimum sustained bandwidth to the non-interfered with device.

Abstract: An apparatus and method for communicating between a controller and a message processing device over a universal serial bus (USB). The apparatus may comprise an interface having a bulk data-out endpoint for receiving a data-out packet from the controller that requests data from the device. The interface also has an interrupt-in endpoint for receiving interrupt-in packets from the controller requesting a status of the requested data from the device. When the requested data becomes available, logic at the interface transmits the status from the interrupt-in endpoint to the controller. In addition, when USB bandwidth so permits, logic at the interface also transmits the data with the status from the interrupt-in endpoint to the controller. Alternatively, where the data is not transmitted with the status, upon receiving the status the controller queries the interface at a bulk data-in endpoint for the requested data.

Abstract: The present invention relates to the attachment of latency-intolerant devices, such as CD-RW devices to a well supported high bandwidth interface on a host computer. A preferred high bandwidth interface is the Universal Serial Bus (USB) which is commonly installed in personal computers manufactured in the late 1990's. A need for both high pre-allocated bandwidth makes use of the Isochronous transfer mode desirable for communication with CD-RW and other devices requiring continuous data transmission. One of a range of data reliability mechanisms is preferably implemented on the connection to the USB to ensure accuracy in data transmission to the various devices connected to the USB.

Abstract: A novel method and apparatus for automatically migrating computer data from one storage technology to another is presented herein. In accordance with a preferred embodiment of the invention, the automated data transfer application detects the insertion of a source storage media into a source storage device and automatically accesses the source storage device to determine the contents of the source storage media. In one embodiment, all files are automatically selected for transfer. In an alternative embodiment, the user selects a set of files to be transferred. The destination storage media is automatically mounted and the set of selected files are automatically transferred to the destination storage media. In a preferred embodiment, an index comprising a set of keys for each selected file is automatically generated and saved along with the selected files on the destination storage media for use in performing searches of content of the transferred files.
