这是我的程序 我用的是avr单片机 自带usb
#include <cstdlib>
#include <iostream>
#include <windows.h>
#include "AtUsbHid.h"
#define Vid 0x03EB
#define Pid 0x2013
using namespace std;
void main(void)
{
HINSTANCE hLib = NULL;
hLib =LoadLibrary(AT_USB_HID_DLL);
if(hLib == NULL){
cout << "no hlib\n";
}
//cout << "ok\n";
if (loadFuncPointers(hLib)==NULL) {
cout << "no load\n";
}
if (DYNCALL(findHidDevice(Vid, Pid)))
{
// timer1->Enabled=true;
// button1->Text="Ready";
// timer1->Start;
cout << "ok\n";
}
else
{
// Can't access leds button if not connected
cout << "no device\n";
}
//system("PAUSE");
// return EXIT_SUCCESS;
}
结果显示 no device
at90usb的id 如我所写vid0x03EB Pid 0x2013 但是为什么我电脑还是只能显示unknown device呢
请大虾指点下
