1. Open Device Manager
  2. Remove Old Com ports and USB devices: Proceed to step 2 of this tutorial.
  3. When that is done, still in Device manager, navigate to your problem USB cable (it should have a yellow exclamation mark on it)
  4. Remove it, and then reinstall the driver
  5. If that driver will still not work then:
  6. Right click on it, and choose update driver.
  7. Click Browse my Computer...
  8. Click Let me pick from a list...
  9. A list of all of the drivers should show. Choose the oldest Prolific driver on the list. I chose version 3.2.0 from 2007
  10. Install it, and you're done!

If you are using PuTTy, note that when you connect, the COM port may not work as expected. What you should do, if you need to, is go into the Serial options in the main PuTTy window, and turn off flow control.

Everything should work right now.

I have the cable branded Baofeng. I uninstalled the new version and installed v3.2.0.0. Following directions, I unplugged the usb cable, ran the install then plugged the cable back in. Windows did not even see that a new device has been introduced. I had to shave off a little of the connector that plugs into the radio or it would only go in half way. I am sure it is seated fully now....

Help!

If you have a programming cable with a Prolific type chip, be sure to
downgrade your installed driver to v3.2.0.0.
