Michael,
Try configuring the interface, the ft2232 stuff, before the target.
I've had issues before when I configured my board before the interface,
so see if that helps.

Hi everyone,
I am still hoping that somebody can point me into the right direction,
concerning my Problem with the ST32-PerformanceStick. I was hoping that
this would moreless work out of the box, because it is stated in the
documentation that this stick is supported by openocd. There is a
stm32stick target, but I don't really understand why this it is not
working for me.
Is there somebody on the list who is using this Hardware with Openocd???
Thanks
Michael

Hello,
I obviously had both problems. I needed to set the vid/pid in the config
file plus the permission problem. I fixed this and got one step further.
But it is still not working. Openocd is obviously talking to the ft2232
chip but still not to the ST32-PerformanceStick.
My openocd.cfg:
source [find target/stm32stick.cfg]
# ftdi interface
interface ft2232
ft2232_device_desc "STM32-PerformanceStick A"
ft2232_layout stm32stick
ft2232_vid_pid 0x0640 0x002d
gdb_port 4789
and I get the following

You might also have a permission problem in your /proc/bus/usb
(or the new location somewhere in /sys). In this
case, "strace -oa -efile ./openocd" and a careful reading of the
generated "a" file will show this.
Then add a proper /etc/udev/rules.d/XXX file to solve this.
