hid_enumerate prints usage of all devices

[Mola19]

This might be user error by me, or maybe it is already solved, but i couldn't find a similar issue.

My code is

#include <iostream>

#include "hidapi.h"

int main()
{
    hid_enumerate(0, 0);
    std::cout << "---END---" << std::endl;
}

Output:

  ---END---

The numbers seem to be the usage for each hid device.

The weird thing is that they are printed after the code ends.

Whether hid_init(), hid_exit() or hid_free_enumeration() get called doesn't influence this issue.

HIDAPI version: I reproduced this on 0.14.0, 0.11.0 and 0.9.0

very interesting
winapi backend doesn't even have the printf anywhere
is the behavior changes if you you printf instead of cout?

No, it doesn't seem to change anything, neither does removing it
