[Elecraft] K3 USB cable

[Dick Dievendorff]

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.
