Appl. No.:

09/498056

Inventors:

John C. Dunn - Issaquah WA
Kenneth D. Ray - Redmond WA
Firdosh K. Bhesania - Kirkland WA

Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 1342

US Classification:

710 42, 710 11, 710313

Abstract:

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.

International Classification:

G06F 1100

US Classification:

714 43

Abstract:

The invention described in the instant application provides for a failure-recovery module, which permits automatic investigation of possible reasons for the failure and takes corrective action in a manner transparent to the user. The failure-recovery module, which is a software module, is useful in evaluating a device connected to a master-slave bus to determine whether it has failed. In the event the device is still connected to the master-slave bus but is non-responsive, the failure-recovery module resets the device, e. g. , by turning off the power to the affected device and rebooting the device with a cold start. The failure-recovery module diagnoses the failure of a device by determining if the device is still connected to the master-slave bus. Then, the failure-recovery module sets a flag to mark the device as having failed while disabling access to devices downstream of the failed device. If the failure-recovery module is unable to execute successfully, it assumes that the failure causing condition still exists.

International Classification:

US Classification:

Abstract:

The present invention provides a method and computer program product for providing, over a RF link conforming to the Bluetooth specification, a network message protocol which is bus-independent and was originally designed for bus-attached networking devices. One such network message protocol is the NDIS device management protocol. In such a manner, many computer software products designed to operate over a hard-wired (or bus-attached) network can also be used over a Bluetooth wireless network.

International Classification:

G06F011/00

US Classification:

714 39, 714 44

Abstract:

Systems and methods for analyzing transactions on a bus. A software module can cause a trace packet to be generated and sent out on a bus to an invalid address. The trace packet triggers a protocol analyzer and permits the bus data flowing on the bus when the software module detected a problem to be analyzed. The trace packet causes the protocol analyzer to trigger even though the bus protocol is normal and the protocol analyzer would not otherwise trigger. The trace packet can be used to analyze and debug communications flowing on a bus when the software module detects a problem.

International Classification:

G66F 1/26

US Classification:

713323, 713310, 710 15

Abstract:

A method and system for asserting power control over one or more hardware devices connected via a bus. The invention includes a method and system for signaling and waiting to suspend a first device connected to a second device. The invention also includes a method and system for suspending a tree of devices with one or more of the devices hierarchically organized as parent devices and child devices in the tree. A controller at a root of the tree receives an idle request from one or more of the child devices and suspends all devices in the tree after receiving an idle request from each of the child devices. The invention also includes an input/output control (IOCTL) data structure for communicating the idle request.

International Classification:

H04Q 7/24

US Classification:

370338, 711123

Abstract:

A method and apparatus to decrease the amount of time it takes to obtain friendly names of Bluetooth devices is presented. A name server caches friendly names for devices that it has acquired from other devices or from other name servers. The name server is any device that caches friendly names of Bluetooth devices and that makes the friendly names available to other devices. A requesting device determines if a name server has responded to an inquiry command. If a name server has responded, the device gets the friendly names the name server has cached and requests the friendly names of devices that responded that have not been cached by the name server. Identification of a name server is accomplished by embedding a marker in the friendly name field after the null character to indicate that the device is a name server.
