usb4java - USB error 5: Unable to read config descriptor: Entity not found

Делаю дамп устройств. Получаю такую ошибку:

Exception in thread "main" org.usb4java.LibUsbException: USB error 5: Unable to read config descriptor: Entity not found
    at com.tsyklop.usb.Usb.dumpConfigurationDescriptors(Usb.java:197)
    at com.tsyklop.usb.Usb.dumpDevice(Usb.java:254)
    at com.tsyklop.usb.Usb.dumpDevicesList(Usb.java:158)
    at com.tsyklop.Main.main(Main.java:79)

код такой:

public void dumpDevicesList() {
        try {
            for (Device device: list) {
                System.out.println("\n=======================\n");
                dumpDevice(device);
                System.out.println("\n=======================\n");
            }
        } finally {
            LibUsb.freeDeviceList(list, true);
        }
    }
    private void dumpConfigurationDescriptors(final Device device, final int numConfigurations) {
        for (byte i = 0; i < numConfigurations; i += 1) {
            final ConfigDescriptor descriptor = new ConfigDescriptor();
            final int result = LibUsb.getConfigDescriptor(device, i, descriptor);
            if (result < 0) {
                throw new LibUsbException("Unable to read config descriptor", result);
            }
            try {
                System.out.println(descriptor.dump().replaceAll("(?m)^", "  "));
            } finally {
                // Ensure that the config descriptor is freed
                LibUsb.freeConfigDescriptor(descriptor);
            }
        }
    }
    private void dumpDevice(final Device device) {
        // Dump device address and bus number
        final int address = LibUsb.getDeviceAddress(device);
        final int busNumber = LibUsb.getBusNumber(device);
        System.out.println(String.format("Device %03d/%03d", busNumber, address));
        // Dump port number if available
        final int portNumber = LibUsb.getPortNumber(device);
        if (portNumber != 0) {
            System.out.println("Connected to port: " + portNumber);
        }
        // Dump parent device if available
        final Device parent = LibUsb.getParent(device);
        if (parent != null) {
            final int parentAddress = LibUsb.getDeviceAddress(parent);
            final int parentBusNumber = LibUsb.getBusNumber(parent);
            System.out.println(String.format("Parent: %03d/%03d", parentBusNumber, parentAddress));
        }
        // Dump the device speed
        System.out.println("Speed: " + DescriptorUtils.getSpeedName(LibUsb.getDeviceSpeed(device)));
        // Read the device descriptor
        final DeviceDescriptor descriptor = new DeviceDescriptor();
        int result = LibUsb.getDeviceDescriptor(device, descriptor);
        if (result < 0) {
            throw new LibUsbException("Unable to read device descriptor", result);
        }
        // Try to open the device. This may fail because user has no
        // permission to communicate with the device. This is not
        // important for the dumps, we are just not able to resolve string
        // descriptor numbers to strings in the descriptor dumps.
        DeviceHandle handle = new DeviceHandle();
        result = LibUsb.open(device, handle);
        if (result < 0) {
            System.out.println(String.format("Unable to open device: %s. " + "Continuing without device handle.", LibUsb.strError(result)));
            handle = null;
        }
        // Dump the device descriptor
        System.out.print(descriptor.dump(handle));
        // Dump all configuration descriptors
        dumpConfigurationDescriptors(device, descriptor.bNumConfigurations());
        // Close the device if it was opened
        if (handle != null) {
            LibUsb.close(handle);
        }
    }

ошибка возникает в функции dumpConfigurationDescriptors; Мне показывает одно устройство, а на втором выдаёт ошибку.
