Patent number: 8266362Abstract: 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.Type: GrantFiled: June 1, 2011Date of Patent: September 11, 2012Assignee: Microsoft CorporationInventors: Firdosh K. Bhesania, Glen T. Slick, Randall E. Aull, Mark E. Maszak

Patent number: 7685322Abstract: Port number emulation for wireless Universal Serial Bus (USB) connections is provided. Virtual USB port numbers are emulated and associated with external devices that are wirelessly connected to a host device. The associations are maintained in a data structure. When a wireless external device connects with the host device after a period of disconnection, the emulated port number associated with the wireless external device is identified. The virtual port number is provided to a software component in the host device so that the external device can resume interaction with software components in the host device across enumerations. In one example implementation, the virtual USB port numbers are provided to a plug and play manager, which handles the wireless USB devices in a manner similar to wired USB devices.Type: GrantFiled: February 28, 2006Date of Patent: March 23, 2010Assignee: Microsoft CorporationInventors: Firdosh K.

Patent number: 7650406Abstract: 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.Type: GrantFiled: April 26, 2006Date of Patent: January 19, 2010Assignee: Microsoft CorporationInventors: Randall E.

Patent number: 7263573Abstract: In a wireless USB data transfers over UWB, software configures hardware thresholds to control data transfer in a manner that uses bandwidth for good connections over bad connections, given the high error rate experienced with wireless USB. Periodic transfers are first attempted before asynchronous transfers, as long as the periodic transfers are successful. When failures are occurring, the hardware includes a mechanism having a software-configurable threshold specifying the number of errors a given endpoint can tolerate before it is paused in the schedule. By pausing transfer attempts that are likely to again fail, endpoints with successful transfers are favored over those experiencing errors. When the number of active transfers pending exceeds a software-configurable notification threshold for isochronous endpoints, the hardware notifies the software of this state, corresponding to a low-buffer condition at the receiver.Type: GrantFiled: December 8, 2006Date of Patent: August 28, 2007Assignee: Microsoft CorporationInventors: Randall E.
