Hi;
Before you install Cisco ACU, you need (1) libsigc++ and (2) gtkmm to be installed on you computer, you can use YaST to install libsigc++ and Yast will auto select gtkmm for you.
Goto
www.cisco.com/public/sw-center/sw-wireless.shtml
follow the instruction to download the ACU driver from Cisco, after download use winzip to unzip it and
use Linux tar to untar it, follow the instructions in the readme file to install the ACU.
goo luck.
