Update: the green channel (TXD) was not soldered correctly. After resoldering, the cable works very well. Thanks for your help anyway!

Was interested in this topic since I purchased an FTDI232 USB-JP1 cable a year or so ago, and could not get it to work on a win8.1 computer.

I confirmed the wiring (as documented in this thread) both by checking the color codes as well as opening the cable and confirming the CB pinouts.

As part of the process, I downloaded and installed a couple of drivers, but had no success with that either.

I then purchased a second cable based on a forum recommendation and that one worked out of the box.

Returning to JP1 fun and games this week, I pulled both cables out and confirmed that only the second cable worked.

Then, a couple of days ago, I moved back to my office which has a win10 computer and tried both cables on that computer. I was surprised that both cables worked with the default win10 drivers.

Obviously this points to a driver problem in Win8.1

Hope that this information is useful,
Beverly Howard

(why win8.1? because win10 does not support Windows Media Center)

That's an interesting discovery.

Try this driver and see if it makes any difference. Maybe the 32-bit driver works better, even on a 64-bit system?

Thanks... driver downloaded, but it may be a few days before I get back to the win8.1 machine. Will report back.
