Automatic Regitsration of Devices to SCC

How can we register devices automatically to SCC. To be more specific, I don't want to register the devices from Sybase Control Center, instead want to make it from device with unique device name

Some details:

1. Went into the HWC Workflow Settings and entered the details like, Server, Farm ID, etc

2. Selected Automatic Registration Option

3. Entered Admin User/Pass supAdmin and s3pAdmin

4. It registers the devices on SCC, but every device name will be supAdmin in SCC then.

Question:

In order that we have the unique device name, what needs to be done.

Tried:

Tried by creating the LDAP profile Security configuration and then using the unique username/password, but it still didn't work.

Please suggest as to how this can be done.
