I haven’t downloaded from my UV-5r for quite some time but today I downloaded the latest version of Chirp, plugged in the cable and I get the following error thrown up by Chirp - “could not open port COM3: [Error 2] The system cannot find the file specified.”
.. and this error for the port in Device Manager of Windows 10 .. “This device cannot start. (Code 10)
It appears that you have a programming cable with a (counterfeit) Prolific type chips. When you first got it, you probably had to download, install and select the older (2007) Prolific v3.2.0.0 device driver to get it to work because Prolific device drivers since 2008 are intentionally incompatible with counterfeit Prolific chips.
You have either plugged the programming cable into a different USB port causing it to be configured with the latest Prolific device driver or Windows 10 has, on its own, decided to upgrade the device driver back to the latest version. In either case, all you have to do is to go back into Device Manager and choose the older v3.2.0.0 device driver again.
Basically you will be repeating steps 6 through 11. http://www.miklor.com/COM/UV_Drivers.php
If you don't want to deal with this again in the future, you can get a programming cable with a different brand of USB-to-TTL chip. FTDI chip based programming cables are popular for this reason.
