I am trying to get signalyzer lite to work with openocd and eclipse. I 
installed the drivers and the device shows up under device manager usb 
controllers and the virtual com port also.

I configure under external tools and run it.
This is what I get:

Open On-Chip Debugger 1.0 (2009-02-14-12:53) svn:1372

BUGS? Read http://svn.berlios.de/svnroot/repos/openocd/trunk/BUGS

$URL: svn://svn.berlios.de/openocd/trunk/src/openocd.c $
Error: unable to open ftdi device: 2
Error: ListDevices: 2

Error: 0: "Signalyzer LITE A"
Error: 1: "Signalyzer LITE B"
Runtime error, file "command.c", line 456:

the cfg file is:

interface ft2232
ft2232_device_desc "Signalyzer A"
ft2232_layout signalyzer
ft2232_vid_pid 0x0403 0xbca1

I tried openocd 717 and same thing.

Hello Chris,

I could imagine that your fault is the following line:

ft2232_device_desc "Signalyzer A"

Do you have a LITE version? In this case try:

ft2232_device_desc "Signalyzer LITE A"

Only an idea...

The errors are different now.

Error:   ft2232.c:1419 ft2232_init_ftd2xx(): unable to open ftdi device: 
Error:   ft2232.c:1434 ft2232_init_ftd2xx(): ListDevices: 2

Error:   ft2232.c:1436 ft2232_init_ftd2xx(): 0: Signalyzer LITE B
Error:   ft2232.c:1436 ft2232_init_ftd2xx(): 1: ˜b?

If I try Signalyzer LITE B then I don't get these errors but errors 
trying to read bytes.

I think the PID is wrong. Here is my interface config for Signalyzer:
interface ft2232
ft2232_layout signalyzer
ft2232_vid_pid 0x0403 0xbca0
ft2232_device_desc "Signalyzer LITE A"
