Register event handlers on the DeviceWatcher object. Using selector based on these class and subclass codes no device is found by DeviceInformation.FindAllAsync(selector). This documentation is archived and is not being maintained. In the code-behind for MainPage.xaml, include the Windows.Devices.HumanInterfaceDevice and Windows.Devices.Enumeration namespaces. // MainPage.xaml.cs using Windows.Devices.Enumeration; using Windows.Devices.HumanInterfaceDevice; Here is the code to retrieve the HID devices: private async void buttonListHIDDevices_Click(object sender,
The sample changes the blink pattern (SuperMUTT) and seven segment display (OSRFX2) by using control transfers. UsbEndpointDescriptor Derives information from the USB endpoint descriptor of the endpoint, such as type, direction, and endpoint number. The app can get a reference to the EventHandlerForDevice singleton and can access the UsbDevice by using EventHandlerForDevice::Current->Device. Windows Runtime Api Download He has formerly worked at Microsoft in the Lync team and in the .NET team (in the Base Class libraries and the Debugging and Profiling team).
Step 7—Study your USB device layout. (Recommended) Step 8—Extend the app to get and show USB descriptors in the UI. Implements a private OnSyncWithDeviceCompleted event handler to handle the transition from background tasks to foreground app when the background task has completed. UsbReadOptions Defines constants for configuration flags that can be set for a USB pipe that the host opens for a USB bulk IN endpoint.
