UsbHostController Class

Package: GHIElectronics.Endpoint.Devices.UsbHost
Namespace: GHIElectronics.Endpoint.Devices.UsbHost

The USB devices plugged into the board, directly or through hubs. One event for each thing a device gives: a keyboard with a touchpad gives Keyboard and Mouse, a webcam gives Webcam and Audio (its microphone). DeviceName is what to open it with (see UsbHost.DeviceType). The events come on the library's USB thread. USB drives come as MassStorage: use StorageController (GHIElectronics.Endpoint.Devices.Storage) for them. A controller stays alive until it is disposed.
