EKK-LM3S9B0 usb_dev_bulk driver problem with Vista

Hi,
I am trying to get the usb_dev_bulk example project to work under Vista Home-Premium 64 and I get an error message that the generic bulk driver has a 'problem'...

When doing the exact same sequence of things with my XP computer, I'm able to get the example running fine.

Here is what I do:

1) set the power switch on the EKK to 'EXT'.

2) connect the BC-ICDI board to the computer.

3) connect hyperTerminal to the FTDI com port.

4) compile the usb_dev_bulk Keil project. Download. Run.

5) connect the EKK to another usb port.

6) windows detect the new USB device and ask for the drivers. I point to the SW-USB-win-4694 drivers downloaded from Luminary website.

6.1) on XP, the drivers install fine and the new device appear as 'Generic Bulk Devices' in the Device Manager. I can then run the usb_bulk_example.exe and get the returned string in capital letter. TX and RX info also appear in the HyperTerminal window.

6.2) on Vista, the driver fails to install and I am told that there is a 'problem' with the device. The application does not see the device either.

Any idea?

Thanks a lot!
Dave

Sorry for the problems you are experiencing! Unfortunately this one has a simple explanation (not that it will help you much). Our USB drivers and Windows-side example applications only currently support 32 bit versions of Windows. The driver INF files provided will install the low level subsystem drivers for 64 bit flavors (WinUSB or libusb-win32 depending upon the device) but they do not contain 64-bit implementations of the lmusbdll.dll or lmdfu.dll libraries.
