AUS is irrelevant to using ASDM launcher from CSM.
If you are trying to launch ASDM from CSM you need to go in CSM client, right click on the device and use the "Launch Device Manager" option.
The device needs to be open for HTTP, it needs to allow http from the CSM server ip address, CSM should have the right device credentials under Device Properties.
The computer that is running the CSM client need to have the ASDM launcher installed also.
I hope it helps.
