EKC-LM3S9B92 and OpenOCD (ubuntu)

I am trying to set up openocd connecting to the EKC-LM3S9B92 TI dev board.

This is what I did:

downloaded OpenOCD 0.5.0 from Sourceforge.

downloaded and installed libftdi-0.19.tar.gz. Copied ftdi.h to /usr/lib.

All the tutorials that I found talk about a ./bootstrap that in my download of openocd does not exist: skipped this point.

Then (in openocd directory):

./configure --enable-maintainer-mode --enable-ft2232_libftdi

make

sudo make install

sudo openocd -f tcl/interface/luminary-icdi.cfg -f tcl/target/stellaris.cfg

gives:

Error: unable to open ftdi device: device not found

I spent one day being sure that the vid and pid match with lsusb (they do, I had to change the pid).

The luminary-icdi.cfg listing is:

interface ft2232
ft2232_layout luminary_icdi
ft2232_vid_pid 0x0403 0x6010
ft2232_device_desc "Luminary Micro ICDI Board"

Then I suddenly found a strange thing: if I change the fourth line to:

ft2232_device_desc "Dual RS232"

then I get:

Info : only one transport option; autoselect 'jtag'
500 kHz
Info : clock speed 500 kHz
Info : JTAG tap: lm3s.cpu tap/device found: 0x4ba00477 (mfg: 0x23b, part: 0xba00, ver: 0x4)
Info : lm3s.cpu: hardware has 6 breakpoints, 4 watchpoints

and I can telnet 4444, that means it’s working.

Do you have an idea of why this happens? ft2232_device_desc is wrong on the default config?
