NullPointerException thrown if no driver is aviable #34

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
If no drivers are aviable for usb device UsbSerialProber.probeSingleDevice(...) 
method throws NullPointerException.

After small change in implementation of this method (additional if) everything 
looks ok.

Proposed new wersion of the method, commented additional line if 
(probedDevices!= null)
-----------------------------------------------------------------------
public static List<UsbSerialDriver> probeSingleDevice(final UsbManager 
usbManager,
            UsbDevice usbDevice) {
        final List<UsbSerialDriver> result = new ArrayList<UsbSerialDriver>();
        for (final UsbSerialProber prober : values()) {
            final List<UsbSerialDriver> probedDevices = prober.probe(usbManager, usbDevice);
            if (probedDevices!= null)          \\additional line to solve the problem
                result.addAll(probedDevices);
        }
        return result;
    }
