BBB boots but I cannot connect to it.

Hi group
I have a problem.
My BBB works well and I can connect to it from one computer over USB (XUBUNTU).
But on another computer I cannot. I have a minimal Ubuntu install there, and do not want to install everything.
I guess I am missing some packages, any tips what it could be?
Thanks.
Petro

Hi guys I have solved it.
I had all soft in place, the problem was with network connection.
On the computer with minimal ubuntu, WICD is used for network managment.
There eth0 is writen into settings, and it does not care if eth1 appears.
If i feed eth1 to wicd client as a wired network device it works perfectly.
Hope it will help somebody.

Best.
Petro
