[android-developers] Re: USBConnection: bulkTransfer OUT => after sending 10-15 x Data's every 4 seconds = USB is disconnected, every time.

UsbDeviceConnection usbConnection = usbManager.openDevice(device);

UsbInterface usbInterface = device.getInterface(0);

UsbEndpoint usbEndpointIN = null;

UsbEndpoint usbEndpointOUT = null;

for (int e = 0; e < usbInterface.getEndpointCount(); e++) {

UsbEndpoint ep = usbInterface.getEndpoint(e);

if (ep.getType() == UsbConstants.USB_ENDPOINT_XFER_INT) {

if (ep.getDirection() == UsbConstants.USB_DIR_IN) usbEndpointIN = ep;

else usbEndpointOUT = ep;

}

}

int receive = -1;

temp = ByteBuffer.allocate(16);

while(true) {

int send = usbConnection.bulkTransfer(usbEndpointOUT, buf, buf.length, 1000);

Log.i("Test","" + send);

receive = usbConnection.bulkTransfer(usbEndpointIN, buffer.array(), buffer.array().length, 1000);  

Log.i("Test","" + receive);

}
