I just tried out Freddie's openocd 0.4.0 binary with
the release 1.1.14.3 driver/dll and it seems to work
fine. I am using the filter driver and tested under Vista 32bit.
This means I am still using the FTDI driver but with libusb0.sys
as the filter driver on top of the FTDI driver.

You may want to give it a try. Install back the FTDI driver from
your vendor. Then install libusb-win32 filter driver 1.1.14.3 from
Sourceforge. Then run the test program and it should show
something like following (mine is the EK-LM3S1968 board).
In general, I would not recommend the filter driver for normal
users, but in this case, you may want to give it a try. We have
made quite some improvement on the filter driver so that now
it works under Vista and Win 7 as well (but still it is not
compatible with some USB device).
