Hi Nath!
 
It seems that we both have the same problems installing Suse Linux V7.0! I am working with another brailledisplay, but I made the same experiences... the brailledisplay was detected and than... nothing! I already contacted the support but no answer! Well, I think we have to wait a little for the answer :-(. But I can tell you, that I am a bit disapointed. Hope they won't let us wait to long. 
 
Bye Christian
