twain driver and duplex scan

Hello all,
I am writing a VB6 app to complete work orders as the forms are turned in. I want to have the app scan the work order (8.5 X 11) duplex and save to a work order file number . The scanner is a docketport 485. Is there a free twain driver out there , I want to scan duplex , pdf and searchable.

Thanks all
