<div dir="ltr"><div>I think the device manager only looks at the USB "manufacture ID" value of the chip in the product, while the driver looks for a particular serial number sequence or something similar. The chip manufacturers, like FTDI and Prolific, are just trying to protect their IP (intellectual property) so the cloners don't rip them off. I was an embedded systems and software engineer for 40 years, retiring last year. There is a software tool that FTDI used to have on their website that could be used to check if the product was using a genuine FTDI or clone chip. I've had the Linux version of the tool for many years, so haven't had a reason to see if it's still available.</div><div><br></div><div>Larry AC8YE<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Mon, Jul 23, 2018 at 5:19 PM, randy true <span dir="ltr"><<a href="mailto:w4rttrandy@outlook.com" target="_blank">w4rttrandy@outlook.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<div>A similar situation also exists with cable using FTDI USB-to-serial chips. This is another case of a cable manufacturer using a clone (counterfeit) chip instead of a genuine FTDI chip, and FTDI drivers for several years have not worked with the clone
chips. I don't know if an older FTDI driver can be found that will use the clone chip, but other Chirp users may be able to guide you. As soon as I receive a new cable I check it to be sure it used a genuine FTDI chip. If it's a clone chip, I return the
cable to the vendor.</div>

<div>Hi Randy, <br>
</div>
<div><br>
</div>
<div>You didn't say which OS your computer runs, so I''l assume it's Windows. If you have it set to install updates automatically, or the OS is Windows 10, then Microsoft has probably replaced the driver with a different one that doesn't like the cable. This
typically occurs with cables that use the Prolific USB-serial chips. Many cheap cable use clone chips that newer drivers detect and will ignore because they aren't Prolific chips.</div>
