摘要:
The following system and procedure for specifying an extended configuration descriptor includes a USB device that responds to device requests from a host. In response to receiving a host-specific device request that specifies a predetermined index, the USB device returns an extended configuration descriptor to the requester. The extended configuration descriptor includes information that can be used by the requestor to control the USB device. When the USB device is a composite device, the extended configuration descriptor includes function information corresponding to a plurality of sub-devices. Each function comprises one or more interfaces.
摘要:
A USB device is configured to support a non-USB-defined device request that is specific to an application program or operating system. The device request is supported by using a device-specific or vendor-specific request code, which is allowed to vary from device to device. To determine the proper request code, the host performs a GET_DESCRIPTOR device request, specifying a predetermined string descriptor. The requested string descriptor designates the request code to be used in the non-USB-defined device request.

Systems and methods for specifying extended configuration descriptor information in a Universal Serial Bus (USB) device are described. In one aspect, an extended configuration descriptor is provided in firmware of a USB device. The extended configuration descriptor includes a set of non-standard class codes. Responsive to receiving a host-specific device request, the USB device communicates the extended configuration descriptor to a requestor.
摘要:
The described system and procedure provide for storing device-specific UI information into firmware on a USB device. Responsive to receiving a host specific device request, the USB device communicates the device specific information to a requester such as an operating system or other computer program application. Thus, the system and procedure allow OEMs/IHVs to provide additional brand specific information in a USB device in a format that can be determined by an operating system. Moreover, the system and procedure allows OEMs/IHVs to store device-specific UI information in the firmware of a USB device such that installation media does not need to be distributed with each USB device to specify the device-specific information.
摘要:
A computer peripheral has a processor, non-volatile memory, and a plurality of controls. The non-volatile memory holds control mappings corresponding to a plurality of application program genres. The control mappings indicate actions to be performed in application programs of particular genres in response to actuation of particular controls. The control mappings indicate controls by unique string indexes that are also used in HID control descriptors associated with the computer peripheral.
摘要:
Systems and methods to specify device specific user interface information in firmware of a USB device are described. In one aspect, a USB device receives a host-specific device request from an application executing on a computing device coupled to the USB device. The USB device identifies a host-defined string descriptor defined by the application. The host-defined string descriptor is stored in firmware of the USB device.

Device connection routing for controllers is provided. A computing device is configured with multiple controllers that provide connections for peripheral devices. The controllers enable the peripheral devices to interact with the computing device through a bus. Each device connection is routed to one of the multiple controllers based on one or more pre-determined factors. These factors may include load-balancing, power saving, quality of service, data flow requirements, and the like. Device connection routing may be dynamically managed to respond to changing states of the peripheral devices and the controllers. The device connection routing may be performed for controllers associated with any type of wired or wireless buses, such as Universal Serial Bus (USB), IEEE 1394, Secure Digital Input/Output (SDIO), and the like.

A secure association may be established between a first device and a second device for providing secure communication. When the secure association is to be terminated, a first device may save an indication that termination of the secure association is pending, if it is unable to communicate with the second device at that time. At a later time, the first device may communicate with the second device to notify it that the secure association is to be terminated. After the second device has been notified, the secure association may be terminated by the first device.
摘要:
An interoperability assessment between two or more devices can be based on the devices' specifications and on empirical evidence of interoperability. Comparisons between the devices' capabilities can provide an initial assessment of interoperability, which can be further supported, or contradicted, by empirical evidence. Interoperability determinations can leverage existing data collection, such as error reporting and user identities to obtain estimates of empirical usage of devices, and to provide for a level of automation for requesting users. Interoperability determinations can also be offered, with identity protection limitations, for users other than the requesting user to facilitate gift-giving or agent purchasing.
摘要:
A system for identifying data connection attributes is disclosed. The system comprises a connection monitor that identifies an operational attribute of a data connection. The system also includes a signal module that activates operation of a status indicator of the data connection such that a manner of operation of the status indicator is associated with the operational attribute. Methods for operating the system are also disclosed.
