How to get information about the flash drive from which the program is launched?

Question

C++ / C#

The program is launched from a flash drive, you need to find out:
1. The letter of the flash drive;
2. Serial number (the one after Vid and Pid of the device or the entire code);
3. GUID number of the flash drive.
Help, please, who than can.

Answer 1

The letter of the flash drive can be obtained immediately from the main parameters:

#include<stdio.h>

int main(int n, char** args)
{
  printf(args[0]);
}

We get the path of the working directory, parsing which we find out the letter.
Then, with the help of WinApi or some other, you can find out everything else.
PS I don’t know yet how to find out the rest, you need to dig

Answer 2

Alternatively, upload one of the specialized utilities to the USB flash drive, which you can take from the usbdev.ru website. It is possible to find a utility that writes a log, and then read this log through your program. Well, or directly "connect" to the utility for collecting information and receive data from it.
