摘要:
Safe mode operation for portable devices supporting multiple protocols includes a portable device that supports multiple protocols, such as a base functionality protocol and an enhanced functionality protocol, reporting to a host device that the portable device supports only a single protocol (e.g., the base functionality protocol). This single protocol will be used for subsequent communication between the host device and the portable device. This reporting to the host device that the portable device supports only a single protocol can be triggered, for example, by an appropriate button(s) on the portable device being pressed when the portable device is powered on.
摘要:
In accordance with certain aspects of the automatic protocol determination for portable devices supporting multiple protocols, a portable device detects which one of the multiple protocols is being used by the host device for subsequent communication with the portable device. This detection is based on the content of a command received from a host device. The detected protocol is then used by the portable device for subsequent communication with the host device. The host device may also send, to the portable device, a notification of which of the multiple protocols is being used by the host device.

Automatic protocol migration when upgrading operating systems includes checking, after upgrading at least a portion of an operating system of a host device, whether a new driver supporting enhanced functionality for a portable device is now available, where a driver supporting base functionality would have been previously used for communicating with the portable device. If such a new driver supporting enhanced functionality for the portable device is now available, then the host device installs the new driver supporting enhanced functionality for the portable device.

Processes for presenting a current state of a device having device storage connected with a host system are provided. In some processes, device manufacturers or vendors define a set of operational states of a device and provide user interface (UI) elements of a custom representation of each state through information stored in the device storage. Initially, the set of states of the device and UI elements associated with each state are received from the device storage. Information regarding a current state is received from the device, and a representation of the current state, which includes the received UI elements, is presented on the host system. In other processes, UI elements of a representation of each state are obtained from a remote system using device identification information. In other processes, UI elements from the device, from the host system, and/or from a remote system are combined to form a state representation.

An integrity unit can be calculated from a first data unit, and a first storage device can be requested to store the first data unit. A second storage device, which can be separate from and/or a different type of device from the first storage device, can be requested to store metadata, which includes the integrity unit, in nonvolatile memory. Also, a second data unit can be received from the first storage device in response to a request for the first data unit. The integrity unit can be received from the second storage device, and the second data unit and the integrity unit can be analyzed to determine whether the second data unit matches the first data unit. Alternatively, a first integrity unit can be stored in a metadata region of a nonvolatile memory block, where the block also stores the data from which the first integrity unit was calculated.
摘要:
Providing for analysis of artifacts of electronic devices to generate data that is substantially unique to a particular device or to a class of devices is described herein. In some aspects, analyzed artifacts are chosen based on reliable reproducibility of such data over many analyses. The substantially unique data can be associated with a particular electronic device(s) to distinguish such devices from other devices. In some aspects, the generated data is first transformed into an identifier, such as a number, word, string of data, etc., to distinguish the electronic device in remote communication, to provide a key in an encryption/decryption algorithm, and so on. The data can be reproduced by reanalyzing the artifacts, and thus need not be stored for future consumption, mitigating risks involved in storing sensitive data.
摘要:
A mechanism and a storage device are provided for registering a component of a computing device, with a user-removably attached storage device and managing sessions between the component and the storage device. The storage device may record time information regarding a beginning and an ending of an activity session with the component. The storage device may determine whether at least a logical block address range of a storage device medium, registered by the component, may have been modified by a different component, since a last session with the component. When the storage device indicates to the component that at least the logical block address range of the medium has not been modified since the last session, the component may trust contents of the medium. The computing device may provide time information to the storage device, such that the storage device may determine whether management operations are to be performed.
