    Perfect for my application

    Pros: Windows 10 recognizes the chip immediately and installs the driver no problems
    Cable communicates with my serial device perfectly.

    Cons: None that I know about.

    24 out of 24 cables tested 100% good. Cannot do better than that. I would recommend this product for its intended use.

    Pros: As with 99.999% of Monoprice cables, this is a great cable at a great price. I had no problems loading the driver. It was instantly recognized as a Prolific chipset USB converter.

    Cons: None.

    Works great on my Windows 7 laptop using driver support file above (http://downloads.monoprice.com/files/drivers/2067_Drivers_Win_XV7_071128.zip).

    questionable drivers at best or bad serial implementation

    Pros: Comes with a db9 to db25 adapter

    Cons: Doesn't Work, Might be a driver issue or just a bad cable.

    I was looking for a lower cost alternative to the SIIG cable I usually buy which I have yet to find an obscure device that it wont work with. However this cable, labeled as being from BYTECC just doesn't seem to want to work. I bought it hoping to retrofit an older set of US Robotics serial modems. The modems are known good. I confirmed that the db9 to db25 adapter works fine with my SIIG cable so that's not the problem. I was looking to use these under Windows Server 2012 R2 but no luck. It doesn't seem to matter what drivers are used, I cannot communicate with any device attached to it. It is not flagged in device manager. It simply doesn't work. So I also tested this Bytecc cable on some test-bed systems to at least determine whether the cable was working or not on any OS in case there were any issues with newer operating systems. I tested it under Windows XP, Vista, and windows 7 all yielding the same results as under 2012 . I tested each using both the provided drivers and the current drivers bundle directly from prolifics website all with the same results. This cable is identified as Prolific chip PL2303-TA by prolifics chip id tool.

    Hello,

    Thank you for your review and my apologies for the issues you have experienced with PID 2067. Unfortunately, it sounds like you may have received a defective product. Since it is not working in windows XP, Vista or 7. Now if you’d like, I can help setup an RMA for a replacement. If you would like me to proceed with the RMA, just let me know and I can get this started right away. Sorry again for the trouble and hope this helps!
