'stm32f103 usb failed with "No open pipes!"

I am trying connect my stm32f103c8 board to PC with several examples from internet, but all of them face the same issue, they can not be installed successfully.

By using "usbview.exe" from windows, I get this error

              ---===>Device Information<===---
English product name: "YunfeiVirtual COM Port  "

ConnectionStatus:                  
Current Config Value:              0x00  -> Device Bus Speed: Full

Open Pipes:                           0
*!*ERROR:  No open pipes!

while a normal usb device may have following:

          ---===>Device Information<===---

ConnectionStatus:

Device Address:                    0x04
Open Pipes:                           3

But if I install usb driver manually, my device is still able to use. Following is my full log for your reference:
