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
