我的环境

我正在使用MinGW编译器(也使用Dev-cpp IDE)在Windows 7上工作,我正在使用从this link下载的预编译的libusb库.

我的设备：这是一款HID触控设备.因此Windows不需要驱动程序.我有一个额外的端点来获取某些调试数据.

我的代码：

我已编译代码列出连接到我的机器的所有设备和USB设备,代码可以工作.现在我添加代码来打开设备,以便获得设备句柄并开始通信.但该函数返回-12即LIBUSB_ERROR_NOT_SUPPORTED.

我该如何解决这个问题？

我在互联网上搜索并没有找到解决这个问题的明确方法.虽然它的代码在Linux上运行得很好.

P.S.：我在下面添加了整个代码. DoList();函数工作正常,但GetTRSDevice();功能在libusb_open(dev,& handle);失败.

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <libusb.h>


libusb_device_handle* deviceHandle = NULL;

int DoList();
libusb_device_handle* GetTRSDevice(void);

int main()
{
    int ret = libusb_init(NULL);
    if (ret < 0) {
        printf("Failed to init libusb");
        return ret;
    }

    DoList();
    deviceHandle = GetTRSDevice();
    if(!deviceHandle) {
        printf("Failed to locate device");
        goto fail_dev_open;
    }

    printf("Device opened");

    libusb_close(deviceHandle);
    fail_dev_open:
        libusb_exit(NULL);

    return(ret);
}

int DoList()
{
    libusb_device **devs;
    ssize_t cnt;


    cnt = libusb_get_device_list(NULL,&devs);
    if (cnt < 0)
        return (int) cnt;

    libusb_device *dev;
    int i = 0;

    while ((dev = devs[i++]) != NULL) {
        struct libusb_device_descriptor desc;
        int r = libusb_get_device_descriptor(dev,&desc);
        if (r < 0) {
            fprintf(stderr,"Failed to get device descriptor");
            return(-1);
        }

        printf("%04x:%04x (bus %d,device %d)\n",desc.idVendor,desc.idProduct,libusb_get_bus_number(dev),libusb_get_device_address(dev));
    }
