[android-developers] USB Host Mode: Multiple Interfaces, not possible to receive data at the same time?

I've written an app to connect an USB Device that have 4 Interfaces
with 4 connected Endpoints:

UsbDeviceConnection usbConnection1 = usbManager.openDevice(device);
UsbInterface usbInterface1 = device.getInterface(i);
usbConnection.claimInterface(usbInterface1, true))

UsbDeviceConnection usbConnection2 = usbManager.openDevice(device);
UsbInterface usbInterface2 = device.getInterface(i);
usbConnection.claimInterface(usbInterface2, true))

.
.
.

But if I start the 4 seperate receivers at the same time (each are 4
runnables):

@Override
public void run() {
try {
while (connectionRunning) {

buffer.clear();
receive = usbConnection.bulkTransfer(usbEndpointIN, buffer.array(),
buffer.array().length, 100);

...then the datas has a delay and didn't get all of the data. If I run
only one receiver all is ok.

Have anyone a solution for this problem?
