[Libusb-win32-devel] Error: unable to open ftdi device

[<Pet...@t-...>]

Hello all,
 
I waant to use a mikrocontroller board communicatin by OpenOCD via USB. 
I´ve installed
https://sourceforge.net/projects/libusb-win32/
<https://sourceforge.net/projects/libusb-win32/>
 
And when I connect that device at USB I see two entries
USB Serial Converter A (Interface 0)
USB Serial Converter B (Interface 1)
 
Both with Driver libusb0 (v1.2.6.0)
USB ID 0403 6010 00
 
I use a config file thm_arduino.cfg with the follwoing entries:
 
interface ftdi
ftdi_device_desc "OOCDLink"
ftdi_vid_pid 0x0403 0x6010
 
and run on console of my Windows Vista Business Service Pack 2 (latest 
version)
 
openocd -f C:\Users\oehler\workspace\Labor3\interface\thm_arduino.cfg -f 
C:\Users\oehler\workspace\Labor3\mrt\board\thm_arduino.cfg
 
But I am getting always the message:
 
Error: no device found
Error: unable to open ftdi device with vid 0403, pid 6010, description 
'OOCDLink', serial '*' at bus location '*'
 
Why OpenOCD can not find that device? What can I do to further check that 
the driver is correct installed?
 
Best regards,
Dr. Peter Oehler
