xilinx cable 3 doesn't talk with pc,but test ok

hello
i built on myself a cable 3 interface,following the xilinx drawing,i checked
in all the possible ways,ohmically,injecting square waves,and then once
connected tho the parallel port i used the option in the Jtag programmer
utility that allows to force level on tdi,sending n clock pulses and so
on,these signals are present on the pins of the fpga and the cable is
connected to the supply(5V),but the pc doesn't see the cable at all
please,anyone can help me?thanks!

Try the different BIOS setup options on your computer for the port in
question. It worked wonders for me, but that was a Parallel IV cable. When
it was set to ECP-mode, everything worked so much better.

Well, try to change the port.  My Cable IV would not work at all on my
"expansion bord" LPT, but it worked on my mainboard LPT. Maybe the opposite
is the case for you ?
