After upgrading to Windows 10 from 8.1 on my Surface Pro 3 the Prolific RS232-USB driver is not functional as it was under Windows 8.1. The device manager reports for this device:

'This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)

Usb 2.0 To Rs232 Cable Driver For Windows 10

Product Description. The USBG-232 will your Laptop or Desktop computer to synchronize your PDA, Digital Camera, Cell Phone or other device currently using a serial port with this USB RS-232 Serial Adapter.

  1. Please be warned that counterfeit (fake) PL-2303HX (Chip Rev A) USB to Serial Controller ICs using Prolific's trademark logo, brandname, and device drivers, were being sold in the China market. Counterfeit IC products show exactly the same outside chip markings but generally are of poor quality and causes Windows driver compatibility issues.
  2. The VCP driver emulates a standard PC serial port such that the USB device may be communicated with as a standard RS232 device. The D2XX driver allows direct access to a USB device via a DLL interface.

Object Name already exists.'

I followed all on-line advice for Code 31 and to no avail deleted the current driver and re-install, re-boot, and search for new hardware it does not fix the problem. I find hints of the driver in the Registry but removing mention of the Prolific device may be problematic since it seems there are other devices I use regularly where removing the entry in the Registry may cause other issues.

As a further comment that is food for thought by Microsoft is that I find the lack of registry repair tool as available in Windows 7 is not a good move by the Technical Staff of Microsoft. You will never get full traction with Windows 10 unless the tools are in place for users to fix problems caused by Windows 10 install to be fixed easily.

When you troubleshoot issues with a serial device, there are some quick tests that you can complete to rule out potential problems. You can test to make sure that the following components are working correctly and are not the source of the issue:

  • Serial cables

  • Serial ports

  • Serial devices

To test your setup components, try the following:

  • Use the serial cable, serial port, and serial device in another setup to see if the problem is with the components or the setup.

  • Use a different serial cable, serial port, and serial device in your setup to see if the problem persists. Ideally, you should test a component that you know works in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.

  • Use short cables when you are testing.

  • Press the Windows key + R, type devmgmt.msc, and press Enter to open Device Manager. Check to see if your device is listed under Ports (COM & LPT).

  • Make sure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number.

  • If you do not see the COM port number in Device Manager see this FAQ for PCI/PCIe expansion cards: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#pci-pcie-cannot-boot-os-or-detect-windows
    or this FAQ for USB devices: https://www.startech.com/support/faqs/technical-support?topic=expansion-cards#usb-cannot-detect-windows

  • If the device is listed with an error, follow the instructions on the website to reinstall the drivers.

Note: Some serial devices work only if the COM port number is between a certain range. For example, COM1 to COM4.
