URS_CONFIG_INIT Initializes a URS_CONFIG structure.
UrsDeviceInitialize Initializes a framework device object to support operations related to a USB dual-role controller and registers the relevant event callback functions with the USB dual-role controller class extension.
UrsDeviceInitInitialize Initializes device initialization operations when the Plug and Play (PnP) manager reports the existence of a device.
UrsIoResourceListAppendDescriptor Appends the specified resource descriptor to the specified I/O resource list object that maintains resource descriptors for the host or function role.
UrsReportHardwareEvent Notifies the USB dual-role class extension about a new hardware event.
UrsSetHardwareEventSupport Indicates the client driver's support for reporting new hardware events.
UrsSetPoHandle Registers and deletes the client driver's registration with the power management framework (PoFx).
EVT_URS_DEVICE_FILTER_RESOURCE_REQUIREMENTS The USB dual-role class extension invokes this callback to allow the client driver to insert the resources from the resource-requirements-list object to resource lists that will be used during the life time of each role.
EVT_URS_SET_ROLE The URS class extension invokes this event callback when it requires the client driver to change the role of the controller.
URS_CONFIG Contains pointers to event callback functions implemented by the URS client driver for a USB dual-role controller. Initialize this structure by calling URS_CONFIG_INIT.
