Most likely this is caused by the driver failing to start, so you  
should try if running the driver in debug mode returns a more useful  
error:

     /path/to/liebertgxt2 -u root -DD -a liebertgxt2

Besides posting of the above, also post the output of 'lsusb' and the  
kernel version you're using. Note that there are a fair number of  
crappy USB to serial implementations. I have good results with PL-2303  
based solutions, so this is generally what I recommend to use.

Note that if you just complain that something doesn't work (without  
providing debug or even error messages) chances are slim that anybody  
is able (let alone willing) to help (I usually ignore them).

Best regards, Arjen
