UsbDevice.GetDeviceSelector Method

Definition

Namespace:

Windows.Devices.Usb

Overloads

GetDeviceSelector(Guid)	Gets an Advanced Query Syntax (AQS) string, based on the device interface GUID identifier, specified by the app. The app passes the string to DeviceInformation.FindAllAsync in order to find a specific type of USB device.
GetDeviceSelector(UInt32, UInt32)	Gets an Advanced Query Syntax (AQS) string, based on vendor and product identifiers, specified by the app. The app passes the string to DeviceInformation.FindAllAsync in order to find a specific type of USB device.
GetDeviceSelector(UInt32, UInt32, Guid)	Gets an Advanced Query Syntax (AQS) string, based on vendor, product, and device interface GUID identifiers, specified by the app. The app passes the string to DeviceInformation.FindAllAsync in order to find a specific type of USB device.

GetDeviceSelector(Guid)

Gets an Advanced Query Syntax (AQS) string, based on the device interface GUID identifier, specified by the app. The app passes the string to DeviceInformation.FindAllAsync in order to find a specific type of USB device.
