On the Xilinx Spartan-3E Starter kit board there is an USB interface to
program the FPGA chip via JTAG. However this part of the schematics is
missing from the documentation:
http://www.xilinx.com/support/documentation/boards_and_kits/ug230.pdf

I remember that someone actually did locate the connections around 2006/2007
and put the schematics online for that section. But I can't locate it.
Someone knows where to find it ..?

(The USB port is wired to the CY7C68013A-100AXC containing an 8051 cpu as
the primary USB interface. I think it's connected to the XC2C64A-5VQ44C
CPLD as well. I have seen the http://rmdir.de/~michael/xilinx/ page too)

There is some discussion (in german) on

Look at the schematics for the SP605 development board. They include
the USB JTAG pages of the schematics, as do a few of the other newer
development boards.
