USB Bulk device application not working on TMDXLCDK138

Hello,

(First, I have looked at similar posts before [partially answered, or inconclusive most if not all] and obviously have exhausted ideas to make it work.)

Problem: I am not able to run the application for the Bulk device example in the Starterware_USB wiki side (Running the Example Application under Buld Device Class section in: processors.wiki.ti.com/.../StarterWare_USB

I downloaded the application SW-USB-WIN and installed it. I downloaded this from: www.ti.com/.../sw-usb-win

I downloaded the drivers SW-USB-WINDRIVERS and unzipped them. From: www.ti.com/.../sw-usb-windrivers. These include several .inf files and security catalog files. Including a usb_dev_bulk.inf file within all those files.

I imported the usb_dev_bulk project from the build directory in here: C:\ti\C6748_StarterWare_1_20_04_01\build\c674x\cgt_ccs\c6748\lcdkC6748\usb_dev_bulk

Built it and downloaded it to the target successfully and ran it.

Connected the TMDXLCDK138 to the PC using a USB cable. On the TMDXLCDK138 side the USB connector I used was the USB OTG (connector J2).

PC running Windows XP SP3 detects device and ask for driver. I point it to the folder where I unzipped all the .inf and catalog files. It seemed to have installed driver successfully. Then it says USB device not recognized. So I run the usb_bulk_example.exe application and it complains with error stating that no device is connected, go connect device and try again.

I have tried this on four different machines. Windows 8.1, Windows 7, Windows XP, and Windows Vista, and none recognize the device (board running usb_dev_bulk.out). They all detect it and finally say " USB DEVICE NOT RECOGNIZED", unknown device. So I am not able to run the example. I have tried uninstalling it and updating the driver, restrating several times etc, with no luck, It is always unrecognized.

On Windows 7 I tried running the hdwwiz and installed the Bullk Device by pointing to the Windows driver folder provided by TI (I took this from a previous post from Norman Wong). It does install it, but complains about Code 10, not being able to start it (this without the board connected or not).

1) I would like to have this one working to see the usb_deb_bulk in action, any hints or guidelines are highly appreciated.

2) It seems, (I may be wrong) I have to run this application demo for the USB in bulk mode in the C6748 using an old Windows XP or Vista machine (which I have and it hasn't work for me anyway). Am I using something TI does not support any more?, Is there a better way to have the USB inside the C6748 running using the C6748?. I need the maximum speed I can get out of USB for my product (480Mbps), I cannot afford using the CDC (115200 bps) or the external FTDI controller driven by UART (12 Mbps), Why TI is not updating this. It seems it happened 6 years ago ...

3) Is there an application demo for usb bulk mode TI can provide for more recent versions of Windows?, say Windows 8.1?.

Thank you,
