Class Device

java.lang.Object

org.usb4java.Device

public final class Device
extends Object

Structure representing a USB device detected on the system. This is an opaque type for which you are only ever provided with a pointer, usually originating from LibUsb.getDeviceList(Context, DeviceList). Certain operations can be performed on a device, but in order to do any I/O you will have to first obtain a device handle using LibUsb.open(Device, DeviceHandle). Devices are reference counted with LibUsb.refDevice(Device) and LibUsb.unrefDevice(Device), and are freed when the reference count reaches 0. New devices presented by LibUsb.getDeviceList(Context, DeviceList) have a reference count of 1, and LibUsb.freeDeviceList(DeviceList, boolean) can optionally decrease the reference count on all devices in the list. LibUsb.open(Device, DeviceHandle) adds another reference which is later destroyed by LibUsb.close(DeviceHandle).
