Examples of org.usb4java.DeviceHandle

org.usb4java.DeviceHandle
Structure representing a handle on a USB device. This is an opaque type for which you are only ever provided with a pointer, usually originating from {@link LibUsb#open(Device,DeviceHandle)}. A device handle is used to perform I/O and other operations. When finished with a device handle, you should call {@link LibUsb#close(DeviceHandle)}. @author Klaus Reimer (k@ailis.de)
