The easiest solution would be to stop using a programming cable with the
Prolific chip.

Purchase a programming cable that uses the FTDI chip. They are available
from multiple sources (BaofengTech.com, BuyTwoWayRadios.com and Valley
Enterprises come to mind).

Build a programming cable with a CP2102 module. I did this using parts
acquired from eBay for under $5.

The next easiest solution would be to not use Windows 8.1.

Download and "burn" CHIRP Live CD to a USB flash drive. The built-in
Xubuntu OS driver for the Prolific chip doesn't care if it is genuine or
not. Use the software called "unetbootin" to "burn" CHIRP Live CD to a USB
flash drive. Be sure to include some "Space used to preserve file across
reboots (Ubuntu only)" so that CHIRP can be updated and your CHIRP .img
files can be saved to the flash drive (I would still copy the .img files to
another medial for backup purposes).


If you still want to try to use your existing programming cable with
Windows 8.1 I would suggest the following.

Plug the programming cable into the USB port that you want to dedicate for
programming. Don't use a port on a USB hub.

Go into Device Manager and click the "Uninstall" button for the driver. On
the next dialog box, be sure to "tick" the "Delete the driver software for
this device" and then click the "Ok" button.

Now remove the programming cable and then reboot.

With the programming cable still unplugged, install the v3.2.0.0 Prolific
driver and then reboot once more.

You now have a computer with the latest driver removed and the v3.2.0.0
driver installed.

Now disconnect your computer from the internet (unplug the Ethernet cable
or turn off wi-fi). With the computer not connected to the internet, plug
your programming cable into the dedicated USB port. The v3.2.0.0 driver
will be installed for this device on this port. It can't be updated because
there is no internet connection to acquire the update.

Good luck,
Jim KC9HI
