Either you are missing the Prolific to Serial USB driver, or the driver is outdated or corrupted. Depending on the issue, you can try out a few solutions to fix this driver issue.

Update Driver

Change COM Port

The cable’s physical condition also matters when connecting your PC to an adapter. Most users use either the FTDI-based or Prolific PL2303-based cables. If you inspect a problem with the quality of your cable, consider switching to an alternate adapter.

What is Prolific USB to Serial Driver “Code 10” Error?

Even after updating your driver, you may encounter the Code 10 error. Code 10 error is when your Windows automatically downloads the wrong driver on your device. The driver version installed on your device must be incompatible with your device, so your device cannot use it to establish any connection. 

You can check if you have this problem through your driver’s Properties. If the device status shows “This device cannot start (Code 10)”, follow these steps to solve this issue:

  1. From your PC, open your browser.
  2. On the search bar, go to Prolific official website.
  3. On the search bar to your left, type in the model number of your USB to Serial adapter and select Go.
  4. Choose the Link for driver downloads. Follow through the onscreen instructions to download the compatible driver with your Windows version.
