stm32 虚拟串口 window7下驱动安装成功

不管是使用STM32官方提供的驱动，还是使用网上下载的.inf文件，在windows7下安装驱动，能够安装上，可以很多时候是出现黄色的小叹号，说设备无法启动，错误代码:10。导致无法使用。
  今天本人就成功地安装上驱动了，很是高兴。原先也是试验了多次，没有成功。就手动修改inf文件，终于成功了！
  成功的关键所在：  USB\VID_10c4&PID_ea60；此处的VID和PID一定要和你程序中使用的ID相同。

  以下是本人使用的inf文件：

修改VID，PID文件的名称及位置:

  文件名称：usb_desc.c

  位置：  就是下边的  idVendor 和 idProduct

   /* USB Standard Device Descriptor */
const uint8_t Virtual_Com_Port_DeviceDescriptor[] =
  {
0x12, /* bLength */
USB_DEVICE_DESCRIPTOR_TYPE,    /* bDescriptorType */
0x00,
0x02, /* bcdUSB = 2.00 */
0x02, /* bDeviceClass: CDC */
0x00, /* bDeviceSubClass */
0x00, /* bDeviceProtocol */
0x40, /* bMaxPacketSize0 */

0xc4,    /* idVendor = 0x10c4 */
0x10,

0x60,       /* idProduct = 0xea60 */
0xea,

0x00,
0x02, /* bcdDevice = 2.00 */
1,    /* Index of string descriptor describing manufacturer */
2,    /* Index of string descriptor describing product */
3,    /* Index of string descriptor describing the device's serial number */
0x01 /* bNumConfigurations */
  };
