Planet Technology no longer supports your product, therefore I couldn't find any official driver releases.
I did, however, manage to find this website which is offering your driver:
http://members.driverguide.com/driver/detail.php?driverid=291459No, you don't have to pay for the driver. Once you click on the driver's file-name to download the driver, select the option, "Download this driver by viewing a series of ads." Afterward press, "Continue > > >."
Once the ads appear, simply scroll to the bottom of the page and click the link reading, "No Thanks." Continue that process until the download initiates.
If you have any further questions, feel free to ask. Let me know if I need to describe any of the steps mentioned above in more detail. If I solved your question, please rate my solution. (-:
