Export contacts from a desktop application to a BlackBerry phone via USB

I have to develop a module that exports contacts from a desktop application to a blackberry address book via USB connection. I read about the IRimDa开发者_JS百科tabaseAccess interface and the other RIM interfaces but I cannot figure out how to get initial access to the contacts database on a BB device from the desktop application.

BlackBerry Desktop Software can do CSV import and export of contacts on the phone. So one option would be to produce a CSV file and then just run the desktop software to import the contacts.

Yes, I know about this option but it should be something like this. When a user clicks a button labeled "Export to my Blackberry" (for example) in some contacts filtering form the contacts to be directly transfered to a Blackberry device connected to the user's computer via USB plus it is not necessary to install any additional software on the BlackBerry device so the contacts transfer to succeed.
