K3 USB cable

Hi
I recently acquired a new shack laptop, Win 10 Home,
connected elecraft USB-RS232 cable to update firmware with the latest
utility.
But unsuccessful, got the message -
<PL2303HXA phased out since 2012, please contact your supplier>

So I ended up doing it no problems with an older Win 7 laptop.
Does anyone have any experience with this or a solution?

thanks

Re: K3 USB cable

You cable likely has a fake Prolific USB to RS232 chip. The latest
drivers will refuse to use it. Where did the cable come from? I don't
think Elecraft used fake chips.

You probably need a new cable to work with the latest drivers.

This is probably a message from a Windows USB driver install. I don’t recall adding that text to the K3 Utility.

Early KUSB cables used a chipset from a company named Prolofic. Their brand fell on hard times, there were reportedly some counterfeits. Device driver support comes from the OS and device vendors, we use what’s there. I suspect Windows 10 no longer supports the Prolific chipset.

We’ve moved on (some years ago, more than 10) to USB to serial adapters that use the FTDI chipset. I’d recommend moving to an adapter with an FTDI chipset. Elecraft’s KUSB is not the only USB to Serial adapter with the FTDI chipset, but it does have jack screws to hold the 9-pin connector to the back of the K3.

The K3 Utility will use whatever driver the OS provides for the selected COM port.

Thanks Dick and Mark for your replies.
My cable was purchased from elecraft,
I will get an FDTI adaptor and see how that goes.
