What is the best way to communicate between PC and USB device

Scenario is, I have an USB device with flash card for storage in it. I am going to write a PC app using c# to communicate/exchange data with this device. Something similar to various SYNC programs

Two options that come to my mind are:

  1. Expose flash card as mass storage device and simply copy the required data
  2. Use CDC-Data

Now, if I use first option, is there any way I can run some autorun.bat file upon connection of this device to check if the required PC app is installed or not and if not installed, guide the user to download from specific website?

If I use the second option, then I think user has to explicitly download required PC app and only then he/she will be able to exchange the data (such as iTune)

Kindly suggest if there is any other way to achieve the same?

Best Regards

Various versions of Windows support an autorun feature, but I think it has been disabled to some extent in later versions because it is a security risk.

I would make it a composite device where one function is mass storage and another function is general (uses WinUSB/libusb). Then put a little downloader called setup.exe on the SD card and tell users to run it to install the drivers and software.
