This warning from Prolific's website regarding fake Prolific USB chips
was noticed in January 2012:
It is recently confirmed that counterfeit (fake) PL-2303HX USB to Serial
Controller ICs using Prolific's trademark logo and device drivers were
being sold in the China market. Counterfeit IC products show exactly the
same outside chip markings but generally are of poor quality and causes
driver compatibility issues (Error Code 10). We issue this warning to
all our customers and consumers to avoid confusion and false purchase.
Please be warned that selling counterfeit products are illegal and
punishable by civil and criminal courts according to the trademark,
copyright, and intellectual properties laws and regulations. Prolific
will take proper and severe actions to cease and confiscate these
counterfeit products. Prolific also prohibits the distribution of any
PL-2303 drivers (including download links) without written permission
Prolific advices end-users to only purchase branded cable products with
company name contact information for service and support in case you
suspect a counterfeit chip inside. You may also contact Prolific to
provide the vendor information.
and this one in May 2012:
Windows 8 is NOT supported in HXA/XA chip versions
(will show yellow mark Error Code 10).
Windows 8 is supported
only in following chip versions:

|The VX-8 and
VX-8D connection is a
proprietary 7-pin design. The Yaesu CT-134 clone cable and the CT-M11
external headset connection cable for the FTM-10R both have the correct
plug attached. In conjunction with a
FTDI TTL-232R-3V3 cable it is easy to make up a suitable lead. See
the 'Connection to the radio' section of the
FTBVX8 Help file
for more details and pictures. The picture on the right is a cable made
|The VX-8G data cable is a simple
wire connection at RS232 levels - no level converter. Then use a
USB/serial adapter if you do not have a serial port on your PC.
||The VX-8G operating manual has details of
the cable in the Appendix, CT-143 Cable Connections. In summary they
are: stereo tip to DB9 pin 2 (radio => PC), stereo ring to DB9 pin 3 (PC
=> radio), stereo sleeve to DB9 pin 5 (GND).

CT-27 clone cable and the mouse port off a dead motherboard.

article by G4TIC. This will work with radios that use a 2-wire
interface e.g. VX-150, VX-170, VX-177, VX-6, FT-1802, FT-1807, FT-2800,
FT-7800, FT-8800, FT-8900.
I have built this circuit myself and it works
fine. A picture of my board is on the right. Because they were already
available I used 1N4002 diodes instead of 1N914 and PN2222A
transistors instead of 2N2222.
Roger Maeder has sent me some files to help with creating a PCB for the
G4TIC interface. See opposite for a) a zip file of the files; b) a
picture of the completed board
