Examples of ch.ntb.inf.libusbJava.Device.open()

ch.ntb.inf.libusbJava.Device.open()

Opens the device and claims the specified configuration, interface and altinterface.
First the bus is enumerated. If the device is found its descriptors are read and the maxPacketSize value is updated. If no endpoints are found in the descriptors an exception is thrown. @param configuration the configuration, see {@link Usb_Config_Descriptor#getBConfigurationValue()} @param interface_ the interface, see {@link Usb_Interface_Descriptor#getBInterfaceNumber()} @param altinterface the alternate interface, see {@link Usb_Interface_Descriptor#getBAlternateSetting()}. If no alternate interface must be set -1 can be used. @throws USBException

      byte[] readData = new byte[data.length];


      // open the device with configuration 1, interface 0 and without
      // altinterface
      // this will initialise Libusb for you
      dev.open(1, 0, -1);
      // write some data to the device
      // 0x03 is the endpoint address of the OUT endpoint 3 (from PC to
      // device)
      dev.writeInterrupt(0x02, data, data.length, 2000, false);
      // read some data from the device
