FTDI - LIBUSB problem

[Stefkos]

Hey

I compiled libusb and ftdi without big problems and want develop software with using chipset FT2232. 0x0403. 0x6010.
Most things went ok, program even found device but when I want open it I receive error: -3 from libusb: LIBUSB_ERROR_ACCESS

My first call from java:
int ok = ftdlib.ftdi_usb_open( con1, 0x0403, 0x6010 );
then JNI:
ret = (jint)ftdi_usb_open( con[ intnumber ], 0x0403, 0x6010 );//vendor, product );
ftdi.c:
if ( ( var = libusb_open(dev, &ftdi->usb_dev) ) < 0)
            {
                __android_log_print(ANDROID_LOG_INFO, "LIBFTDI", "ftdi OPEN USB fail" );
                ftdi_error_return_free_device_list( var, "usb_open() failed", devs);    //-4
            }
and here I cannot open it:
if (hpriv->fd == -1)
    {
        hpriv->fd = open(filename, O_RDWR);
        __android_log_print(ANDROID_LOG_INFO, "LIBFTDI", "Open path ---> %s  - %d", filename, hpriv->fd );
    }
// *** PrimeSense patch for Android ***
   
    if (hpriv->fd < 0) {


How to solve that?

Will this solution work for me?  http://stackoverflow.com/questions/7415346/how-to-give-dev-bus-usb-permissions-for-libusb-android-applications   (works on linux)
Will I have access to device from Java API?

If someone is interested in.
Solution described in url almost works for me (I have one issue and don't know if its hardware problem or software).
At least libusb doesnt return "ACCESS DENIED" information.
