Take a look at libusb Windows port: https://sourceforge.net/projects/libusb-win32/[^] or the original libusb https://sourceforge.net/projects/libusb/[^] The library allows for communication with an USB device from an user-space application. No kernel programming required.

You can use a struct or a class with nested vector of same type structs:

#include <vector>
#include <string>
#include <iostream>

struct TreeNode {
std::string payload;
std::vector<TreeNode> children;
TreeNode(const std::string &p): payload(p) {}
TreeNode() {} // it's a must if we are to store nodes in a vector
};

void walk_tree(TreeNode &node, int indent = 0) {
std::cout << std::string(indent * 4, ' ')
<< node.payload << std::endl;
for (size_t i = 0; i < node.children.size(); ++i)
walk_tree(node.children[i], indent + 1);
}

int main() {
TreeNode a("home");
a.children.push_back(TreeNode("peter"));
a.children.push_back(TreeNode("jane"));
a.children[0].children.push_back(TreeNode("game.exe"));
a.children[1].children.push_back(TreeNode("homework.txt"));
walk_tree(a);
return 0;
}
