I am trying to install OpenOCD with the Amontec JTAGkey but are not having any success. Any help is appreciated!!! 
I have installed the libftd2xx.so.0.4.10 library from Amontec (and can see it with ldconfig -p |grep libftd2)
I can see the Amontec USB device with USB view and can see them in /proc/bus/usb/devices …

I built openocd (svn) with
./configure --enable-ft2232_libftd2xx
when I run openocd I get the following errors…

It seems that it cannot see the JTAGkey. I don’t think it’s a permission problem because I’m running as root.
This is my config file:
# Reference: http://openfacts.berlios.de/index-en.ph … figuration
OpenOCD daemon configuration
telnet_port 4444
gdb_port 3333
#interface

Cannot use device descriptor AND serial number

The Amontec JATGkey has the VID & PID as shown
