TMS320F28069M: Issue with Boot_loader example and running dfuprog.exe program on Windows10

Hi, 

Recently I've been trying to upload my programs to my costume made board using "TMS320F28069UPNT" in order to make the product firmware updatable whenever there's a new version released at the customer side. I've checked successfully my USB hardware functionality with the  "usb_dev_serial" example and bunch of other examples to make sure the USB is functional and working fine. Then I tried to use the USB bootloader by reading "F2806x_USBBL_UG.pdf" and going to the steps mentioned in the document, according to this document I've flashed the "boot_loader" project from MWare in "C:\ti\c2000\C2000Ware_2_01_00_00\device_support\f2806x\MWare\boot_loader" to my microcontroller and installed the windows driver "boot_usb.inf" located in "C:\ti\c2000\C2000Ware_2_01_00_00\utilities\windows_drivers" which supposedly is the latest Windows driver for DFU porpuses.

Now in my windows device manager, I can clearly see the driver installed as below:

now when I try to use "dfuprog -e" command using the dfuprog program located at "C:\ti\c2000\C2000Ware_2_01_00_00\utilities\tools\f2806x\dfuprog\Release" I see: 

I understood this is a pretty common problem existing among C2000 users with windows as I saw in the forum after searching for almost 2 days. Based on the C2000 forum I also tried to do the followings:

1-deactivating windows 10 signature requirement

2- uninstall and install the windows drivers

3- using CONTROLSUIT version of dfuprog.exe

It worth mentioning, since in my device I use internal clock, I had to activate PPL2 clocking to USB and eliminating the TI sample code clock inside "ConfigureUSB(void)" function which is designed for those Launchpads equipped with external crystal as below ( I did the same for usb_dev_serial examples and so on to make them work )

void

ConfigureUSB(void)

{

    /*

    SysCtrlRegs.CLKCTL.bit.XCLKINOFF = 1;

    SysCtrlRegs.CLKCTL.bit.XTALOSCOFF = 0;

    SysCtrlRegs.CLKCTL.bit.OSCCLKSRC2SEL = 0;

    SysCtrlRegs.CLKCTL.bit.OSCCLKSRCSEL = 1;

    while(SysCtrlRegs.PLLSTS.bit.MCLKSTS);

    while(!SysCtrlRegs.PLLSTS.bit.PLLLOCKS);

    SysCtrlRegs.PLL2CTL.bit.PLL2CLKSRCSEL = 2;

    SysCtrlRegs.PLL2CTL.bit.PLL2EN = 1;

    SysCtrlRegs.PLL2MULT.bit.PLL2MULT = 120000000/CRYSTAL_FREQ;

    while(!SysCtrlRegs.PLL2STS.bit.PLL2LOCKS);

*/



    /**Added by me**/



    InitSysCtrl();



    // In this example:

    // PLL2 = INTOSC1 (10 Mhz) * 12 / 2 = 60 MHz

    // In general, for more accuracy, source PLL2 with a crystal or

    // external clock source.

    //

    //InitPll2(PLL2SRC_INTOSC1, 12, PLL2_SYSCLK2DIV2DIS);

    InitPll2(0, 12, 0);



    EALLOW;

    // Enable USB Clock

    //

    SysCtrlRegs.PCLKCR3.bit.USB0ENCLK = 1;



    // Enable PHY

    GpioCtrlRegs.GPACTRL2.bit.USB0IOEN = 1;



    EDIS;



    EALLOW; //only for boot_load code to follow the same order!!!!!

    /*****/



    InitPieCtrl();

    InitPieVectTable();

    EDIS;

    //

    // If the target device has a mux to allow selection of USB host or

    // device mode, make sure this is set to device mode.

    //

#ifdef USB_HAS_MUX

    SetUSBMux();

#endif



    //

    // Configure the USB interface and put the device on the bus.

    //

    ConfigureUSBInterface();

}

So as you might be understood by now I need :

1- To understand where's the problem? Is it the windows drivers? how can I mitigate them?
2- To know whether if there's any other way to update the firmware on C2000 microcontrollers with USB? ( preferably more stable methods)
