Dennis,
What Doug said and the fact that the Chinese plagiarized the Prolific
chip a while back but didn't get an exact copy, so Prolific fixed their
drivers to recognize the fake chips and stop working. That seems to
have caused some people problems with even the legitimate ones like
Elecraft sold originally. I wound up getting a USB programmer for one
of the TYT handi-talkies that had the fake Prolific chip in it. Screwed
up everything for a while. Then I found out that the TYT used the same
type of cable the Kenwood ones do and I went to a real RS-232
programming cable cable from Kenwood that worked just fine.
That could be the problem you're running into.

Maybe the best move is to go with the latest FTDI serial -to-usb cable.
They have improved quite a bit over 6 years or more.

Elecraft switched to FTDI chips in mid-2010, so the Prolific driver
isn't used for more recent cables. This page has drivers for both
chips.

Anyone got a solution to this problem? Barring that, what are people
using
for a USB/serial converter now days since I have used the old KUSB
for many
years now? Thanks.
