Are you using external USB hub to connect your board?

I got a similar error when I tried to connect it through external USB hub.

I tried connecting with kermit
srinath@ubuntu:~$ kermit -l /dev/ttyUSB0
can't open device

Tried with ttyUSB1/2/3 etc. Nothing works

Haven't powered up the board yet, as mentioned in this site.
