안녕하세요?
	Windows C++에서 USB HID 장비를 HidD_SetFeature 함수를 이용하여 다음과 같이 제어하였습니다.
unsigned char feature[9] = {0};
feature[0] = 0;
feature[1] = 0xFE;
if(HidD_SetFeature(hDevice, feature, 9))
 return 0;
return -1;
	이와 같은 제어를 안드로이드에서 하려면 어떻게 해야 하나요?
	UsbManager에서 디바이스 검색 및 오픈까지는 정상으로 되어 product name, manufacturer name 까지는 정상으로 얻었습니다.
public boolean open(UsbManager manager, UsbDevice device)
{
 UsbDeviceConnection connection = manager.openDevice(device);
 if(connection == null)
  return false;
 
 UsbInterface intf = device.getInterface(0);
 // Claims exclusive access to a UsbInterface. 
 // This must be done before sending or receiving data on 
 // any UsbEndpoints belonging to the interface.
 connection.claimInterface(intf, true);
 // getRawDescriptors can be used to access descriptors 
 // not supported directly via the higher level APIs, 
 // like getting the manufacturer and product names.
 // because it returns bytes, you can get a variety of
 // different data types.
 byte[] rawDescs = connection.getRawDescriptors();
 String manufacturer = "", product = "";
 try
 {
     byte[] buffer = new byte[255];
     int idxMan = rawDescs[14];
     int idxPrd = rawDescs[15];
     int rdo = connection.controlTransfer(UsbConstants.USB_DIR_IN
             | UsbConstants.USB_TYPE_STANDARD, STD_USB_REQUEST_GET_DESCRIPTOR,
             (LIBUSB_DT_STRING << 8) | idxMan, 0, buffer, 0xFF, 0);
     manufacturer = new String(buffer, 2, rdo - 2, "UTF-16LE");
     rdo = connection.controlTransfer(UsbConstants.USB_DIR_IN
                     | UsbConstants.USB_TYPE_STANDARD, STD_USB_REQUEST_GET_DESCRIPTOR,
             (LIBUSB_DT_STRING << 8) | idxPrd, 0, buffer, 0xFF, 0);
     product = new String(buffer, 2, rdo - 2, "UTF-16LE");
  byte [] feature = new byte[9];
  for(int i = 0; i < feature.length; i ++)
   feature[i] = 0;
  feature[1] = (byte)0xFE;
//  이것이 제대로 안되네요....
//  connection.controlTransfer(0x20, 0x09,
//             0x0, 0x01, feature, feature.length, 0);
 } catch (UnsupportedEncodingException e)
 {
 e.printStackTrace();
 }
 return true;
}
	여기서 feature를 어떻게 전송해야 하는지 좀 가르쳐 주세요.....
	감사합니다.
