A bridge circuit that is located between a peripheral device and a USB connection to a host. The bridge stores data indicating the amount of power required to execute each particular command. When a command is received, the command is executed if this list indicates that a particular command can be executed with the available power. If the list indicates that the command can not be executed with the available power, the command is either rejected or delayed. The bridge may include a power storage device that accumulates and stores power. In this case the list of commands would indicate commands that can be delayed until the storage device has accumulated sufficient power.

The invention relates to a method for controlling a logic cell of a high-capacity storage apparatus, the high-capacity storage apparatus, a high-capacity storage apparatus driver and a high-capacity storage system, wherein the high-capacity storage apparatus is connected to a master computer through a USB interface. The method comprises: responding to the addition and / or deletion of a logic unit; dynamically managing a logic unit list associated with the logic unit and generating corresponding hot plug events on the large-capacity storage apparatus; and notifying the hot plug events to the master computer. In the invention, the plug and play of the logic unit is realized through dynamically managing the logic unit and generating the corresponding hot plug events as well as notifying the events to the master computer.

The invention relates to a method for starting Windows operation systems from a USB (universal serial bus) mass storage device. The method can solve the technical limitation on the conventional Windows operation systems of not supporting the direct start from the USB mass storage device, and retains all the characteristics, such as capability of installing third party software and drive programs and the like, of the conventional Windows operation system; and the method can be used for using the same set of Windows operation system on different computers in a plug and play mode, or for using the different Windows operation systems on the same computer, thus proving 'portability' for the Windows operation system.

An external power-saving USB mass storage device has a USB interface, a USB controller, an interface unit, a device controller and a memory unit. The USB controller has a sleep mode determination process embedded therein for predicting when a USB host plugged in by the USB mass storage device will not access the memory unit of the USB mass storage device for a prolonged time, and activates a sleep mode of the device controller through the interface unit so as to instruct the device controller and the memory unit to enter a power-down state for power-saving purpose.

A method and system, used with an extended USB computer system, for locking out USB mass storage devices at the desktop. For lockout activation, a switch at each host computer is set, and causes a host-side lockout process to deliver a downstream lockout signal to the host's associated portal. This signal causes a portal-side lockout process to disallow USB data from a mass storage device from entering the network.

Apparatuses, methods, and computer program products are perform features associated with a USB Host port on a media processing device. An apparatus is provided comprising at least one processor and at least one memory including computer program instructions, the at least one memory and the computer program instructions being configured to, in cooperation with the at least one processor, cause the apparatus at least to query a USB mass storage device for all template files stored at the root of the USB mass storage device, the USB mass storage device being connected to a USB Host port of a media processing device. The at least one at least one memory and the computer program instructions are further configured to, in cooperation with the at least one processor, cause the apparatus to receive a selection of one or more of the template files to be processed and send the one or more selected files to a parser of the media processing device to be processed. If the selected file currently being processed comprises a reset command, the at least one at least one memory and the computer program instructions are further configured to, in cooperation with the at least one processor, cause the apparatus to store an indication of the position within the list of selected files where the selected file currently being processed is located; cause performance of a reset of the media processing device; and resume processing from a position in the list of selected files based on the indication.

The two devices are of the type supported by the USB standard protocol, so that during upgrading, any drive program does not need to be installed, a PC client program used for upgrading does not need to be downloaded in advance, and the upgrading mode of the to-be-upgraded device ismore flexible, simpler and easier to operate.

Provided is a method of preventing digital content stored in a universal serial bus (USB) mass storage (UMS) device from being distributed without restriction. In the method, registration data is encrypted in order to allow a UMS device to decrypt and use digital content using time information only within a predetermined term of validity. Accordingly, even if encrypted registration data of a UMS device is disclosed, it is possible to make it difficult for unauthorized devices to store the registration data, thereby preventing content of the UMS device from being distributed without restriction.

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.
