Please try to no TOFU, the messages comes more and more un-readable.
I know that some buggy product do not allow it, but if you can, avoid top posting.

try just 
# modprobe ftdi_sio
instead

Mine works just by pluggin, may be your udev rules are incorrect.

my wheezy box show

You mean notinh about jtag or nothing at all ?

Mine is correct

# ls /dev/ttyUSB* -l

You ma try to :
add you user to the dialout group
verify openoce rules (/lib/udev/rules.d/60-openocd.rules)
