debug board seems not working

[Lin Mac]

hi,

I'm using Freerunner and debug board v3, and trying to use serial console, and Ubuntu 8.04 on my PC.

I have connected the FR and the debug board with the flexible cable. The /dev/ttyUSB0 and /dev/ttyUSB1 doesn't show up, but only /dev/ttyACM0, when I connected both USB of freerunner and debug board to PC, as described in http://wiki.openmoko.org/wiki/Debug_Board_v3.

1. Should the /dev/ttyUSB0 and /dev/ttyUSB1 show up while no FR connected to debug board (and the debug board connected to PC)?
2. Should I flash the debug board? 
Any idea? 

Thanks in advance.
