dm.dump();

What is the expected output? What do you see instead?

===========================================
No device detected.

What version of the product are you using? On what operating system?

Version 0.15 and 0.14 

Windows 7 x64, 32 Bit JVM. 
Tried Nexus 4, Razor I, Motorla Xoom 1 and Transformer Prime on two different 
PCs.

Hi,
 I'm trying to use 0.1.4 and a Java program to get a simple list of files
from a Samsung YP-U3 MP3 player. I can get the device ok, but when I try to
get the files it fails.

One important bit of info, I'm running this on Fedora 10 and using libmtp
v0.3.7-1



My Code:
        PlayMgr mgr=new PlayMgr();
        UsbDevice device=mgr.getDevice();
        if ( device == null ){
            throw new Exception("Unable to locate device.");
        }
        System.out.println("\nDEVICE:\n"+device.dump()+"\n\n");
        String[] files=mgr.getFiles(device);

    public String[] getFiles(UsbDevice dev) throws Exception {
        final Map flist=new HashMap();
        long res;
        res=dev.parseFolder(dev.getAudioFolder(), new IParseTreeNotifier(){ 
                                public long addFile(String fileName, String mtpItemIid){
                                    System.out.println("File:"+fileName);
                                    flist.put(fileName, mtpItemIid);
                                    return 0;
                                }
                                public long addFolder(String name, String id){
                                    System.out.println("FOLDER:"+name);
                                    return 0;
                                }
                            });
        if ( res != 0 ) {
            throw new Exception("error reading device #" + res);
        }
        System.out.println("Got #"+flist.size());
        return (String[])flist.keySet().toArray(new String[0]);
    }


The output is:
   java -classpath bin:jusbpmp-0.1.4.jar com.lrs.PlayMgr

Error log is attached

The following code:
        DeviceManager m = DeviceManager.getInstance();
        m.createInstance();
        m.scanDevices();
        System.out.println(m.getDeviceList());

Results in:

I hereby report the Zen X-Fi as an Device (data above) and I really hope
that this isn't yet another dead mtp implementation for java.

Version 1.4 Win7 64 bit.
I think the only problem here is that the dll has been compiled for 32 bit 
system.

There's any way i could recompile it for 64 bit instead?
After that, could check wich architecture is present and therefore load the 
proper dll at app startup.

greetings

Hey there, do you have the files for compiling libjusbpmp on Windows or is 
there away to create a 
build for windows? I've made some changes the core lib to read other mtp track 
info and would like 
to make it work cross platform.

Would it be possible to add support for play counts to the C++ lib for MTP 
devices? I've modified 
the code to support it but im unable to compile it, its simple changes.
