Are you trying to run your program in Linux thru Wine ? Then you won't find a driver to do that. You'd better develop your application to run natively in Linux.
Do not run Wine and insert you device, go to a Linux Terminal and type dmesg, then copy/paste the output here to see if the device is recognized.
You could probably use libusb to control your device, but it might be easier to start with the link provide by corp769:

I used libusb, because I had to port a USB Video grabber program (using EZ-USB device) in Windows to Linux and I did not have any documentation or source. So I had to capture packets in Windows (with a USB Monitor) and replay them in Linux. It did that by writing a program using libusb API. If you want to go that route you can download the source and study the documentation & samples provided with the code.
