I used open source Packet Capture(Pcap) and Wireshark to view video sent by USB Device.  The device sends 512 Bytes packet about every 200 us.  It's a composite device class.  It's a virtual port and bulk video.  Each monochrome raw frame is 640 x 480.

There is a GUI tool that run in windows that extracts video from this USB device and plays video on the PC.  The company who wrote this GUI tool gave us the source code.  I opened this source code into Visual Studio 2017 Professional version without creating a solution or project.  There are Sixteen projects in this codebase.

There are Two main folders.  They both seem to contain library code.  Their description is as follows:
First Folder -  includes information about bulk processing, command processing, port processing, script processing, and USB header information.
Second Folder name is Video - Library files that contain code on a frame viewer and how to stream video through USB, as well as capturing images off the device.

This code is in C Sharp.  Does this appear to be complete codebase for extracting video frames from USB device?  If yes, how to tell if this code will build and run without any changes?

I think the only way to find out is to try it.
