>Description:
Thanks for updating the openocd port. 

I find that the original source needs to be patched to work with the ATMEL SAM-ICE (a.k.a. Segger jlink) on FreeBSD. In the attached patch the extra find_jlink_device() and usb_open() calls in openocd-0.2.0/src/jtag/jlink.c:jlink_usb_open() are #ifdef'ed out.

There is a lengthy thread at:
http://lists.berlios.de/pipermail/openocd-development/2009-July/009397.html
FreeBSD isn't mentioned. It seems there is a portability problem in libusb.
>How-To-Repeat:
I am using an ATMEL AT91SAM7S-EK baord with the ATMEL SAM-ICE JTAG emulator. Using the following samice.cfg:

# Interface is SAM-ICE
