Can you provide a step-by-step instruction on how to set up the Ad-Hoc network?

The User's Guide provided in the package contains the step-by-step instructions on the Ad-Hoc network setup. Daihinia's driver activates itself when the SSID is prefixed Daihinia (example: Daihinia:Joe's-network).

If you create a public network available to anyone, name it just Daihinia and set it to be an open network with no encryption. This could be done by pressing a button in the Control Application: it will create the network on Vista and later systems and will open the User's Guide on older systems.
