This zip file contained 3 files and obviously I ran PL2303_Prolific_DriverInstaller_v1170.exe file to install Prolific Driver in good faith. Hit the first result (that looks like the official Prolific Page: ) and downloaded PL2303_Prolific_DriverInstaller_v1.17.0.zip. So I used good old trusty and searched for “Prolific Driver”. So yes, Windows didn’t pick up the driver. Plugged in the Prolific dongle and this is what I get via Device Manager: Specific driver for my USB dongle is Prolific PL 2303 Driver (VID_067B&PID_2303) What I did (this didn’t work) This guide should work for Windows XP, Windows 7, Windows 8, Windows 8.1 and Windows 10 and both 32 bit or 64 bit. This guide shows how to fix Prolific USB to Serial or Prolific USB RJ45 Ethernet Code 10 error. I use Prolific USB to RJ45 Ethernet dongle and I found that recently in almost any Windows version, I get Core 10 error. If the radio you are working with appears to be unresponsive even after performing the above steps, you may need to perform a recovery.USB to Serial Adapter – Prolific PL-2303 – 3 ft / 1m – DB9 (9-pin) – USB to RS232 Adapter Cable – USB Serial The driver is now optimized for use with Digi radios.

While these instructions are specifically for USB devices that use FTDI Chip components, it's likely that similar options would be present on other USB to Serial adapters that are also experiencing communication problems.

The following procedure will show you how to reduce the USB transfer sizes and latency timing. Performing a firmware recovery or firmware update may fail unless the driver settings are modified. Digi RF radios operate at lower baud rates than are optimal for these drivers and can cause some communication problems when performing certain tasks. The default configuration for FTDI's drivers are optimized for high speed serial devices. Digi interface boards and USB adapters use an FTDI Chip for the USB to serial conversion.
