pirate-loader_lnx with Bus Pirate from sparkfun.com ? - got no bootloader hello

[ds2k5]

Hello, i did comile the: pirate-loader_lnx ( buspirate/BPv3-firmware/pirate-loader-source ).

Bridged the Connectors so that MODE LED is red if USB-Cable is connected.

sudo ./pirate-loader_lnx --dev=/dev/ttyUSB0 --hello +++++++++++++++++++++++++++++++++++++++++++ Pirate-Loader for BP with Bootloader v4+
Loader version: 1.0.2 OS: Linux +++++++++++++++++++++++++++++++++++++++++++

Opening serial device /dev/ttyUSB0...OK Configuring serial port settings...OK Sending Hello to the Bootloader...ERROR No reply from the bootloader, or invalid reply received: 0 Please make sure that PGND and PGC are connected, replug the devide and try again

sudo screen /dev/ttyUSB0 115200 8N1

did not show anything

if the Bridge is not in before cable connect:

Fixing bootloader/userprogram jumps Opening serial device /dev/ttyUSB0...OK Configuring serial port settings...OK Sending Hello to the Bootloader...ERROR No reply from the bootloader, or invalid reply received: 0 Please make sure that PGND and PGC are connected, replug the devide and try again

so i think this is OK

What did i wrong ? Thanks
