 ===========================



This problem shows up with low end amateur radios too.  There are many 
usually Chinese clones of the Prolific USB to Serial adapter and with each 
new wave of clones Prolific rewrites their driver to shut them down.  You 
may have some luck using an old, even very old driver and not letting your 
PC update the driver.

Connecting the radio to the PC

With the programming software installed, now connect the programming lead to 
the PC. The lead is a Serial-to-USB converter, and the PC should now install 
the drivers.

At this point, my PC complained that it missing a file. It was trying to 
install the "Prolific USB-to-Serial" driver, and missing the file ser2pl.sys 
. In the end, I downloaded this sys file from 
www.floridaprobe.com/usb_install.htm, copied it into 
c:\windows\system32\drivers, and then completed the installation.

When researching this article, I also found drivers for 64-bit operating 
systems here: www.radiogearpro.com/download/USB_Drivers_64_bit_4.2.0.zip

FWIW; the 64 bit drivers don't seem to work with 64 bit XP.
