Thanks Mike, We've been discussing this in a forum bit. Someone pointed out that it's called Interface_B or JTAG B, not MPSSE2.
The latest version of OpenOCD has a few device configurations that use the B interface. Here's where it starts in the source: http://openocd.git.sourceforge.net/git/gitweb.cgi?p=openocd/openocd;a=blob;f=src/jtag/drivers/ft2232.c;hb=HEAD#l2261 I haven't gotten around to compiling and running a chain scan yet, but it's on my todo list. I'll post a patch if we come up with one.
