That Keyer has a USB to serial port chip in it, model FT232RL
manufactured by FTDI. I wouldn't be surprised to find that
Microham is using the same chip (Joe?).
microHAM use FTDI USB UART chipsets. Most of the current designs
use the FT232R but older units used other FTDI chips like the
FT232B. However, the same driver package supports all of the
chipsets.
Note, FTDI support two modes of operation - VCP (virtual COM
Port) and D2XX (DLL calls). The problem K6KR refers to is one
in which some vendors disable the D2XX modes in their drivers
(or distribute older drivers that did not support D2XX).
Fortunately, such irresponsible behavior had generally faded
and FTDI have released "common" drivers for all 32/64 bit
versions of Windows (Windows 2000 - Windows 7) as of 3 Nov
2009.

Subject: [dxlab] USB to Serial Port Adaptors
One of the things that I was surprised and pleased about after
installing Windows 7 is that when I plugged in my K1EL WKUSB
keyer, the
USB driver installed automatically without a hitch and it
worked right
off the bat with no hassle. That Keyer has a USB to serial
port chip in
it, model FT232RL manufactured by FTDI. I wouldn't be
surprised to find
that Microham is using the same chip (Joe?). I just did some Googling
for FT232L and found that there are a number of manufactures
making USB
to Serial port adapter cables utilizing that chip and most
are selling
for between $10 and $20. If any one has tried or is willing
to try one
of those I'm sure members of this group would like to hear about it.
