KUSB(Prolific) and Win7 Problems

I think I read somewhere that Elecraft had switched KUSB production to one
based on FTDI. I'm having fits on Win7-64 keeping my notebook stable with
the Prolific based KUSB.

I couldn't find any mention of an FTDI based device on the Elecraft site.
The driver for download there is still the v1.1 of the Prolific one dated
12/09. That one locked up for me fairly often. I tried the v1.3 from the
Prolific.tw site and it isn't any better.

Suggestions?

I don't think Elecraft produces the cable.

FTDI available at

Elecraft has switched to an FTDI-based version of the adapter. I ordered one recently after confirming that fact with Support. It works like a charm on Vista and, given the experience of others, would likely solve your issues on Win7. The new adapter replaced a Prolific-based adapter from Elecraft that was, basically, unusable with anything but the K3 Utility.

The web site hasn't been updated to reflect the change to FTDI yet.

All KUSB usb to serial adapters currently sold by Elecraft use the FTDI chipset. this is noted directly on the KUSB order line on our order page.

Yes, but what's a bit confusing is that the link to the USB drivers on the K3 software page still tries to download a Prolific driver install package.

The drivers that came with my KUSB (FTDI) seem to work just fine on Vista.

Re: KUSB(Prolific) and Win7 Problems

Probably because some will need to get updated Prolific drivers. It
would be good if the webpage had links to BOTH, and explained how to
determine which USB cable you had, so you knew which link to use. It
would also be good to list the date that Elecraft started shipping the
new version.

Re: KUSB(Prolific) and Win7 Problems

There is information in K3 Utility Help under "Troubleshooting" for USB
adapters that describes how to use the Windows Device Manager to determine
the device driver versions. The Windows Device Manager display of the device
driver version will also show you the chipset vendor, if you wonder who
makes the chip set used in the USB to Serial Adapter you're using.

My understanding is that the diskette included with the KUSB (FTDI version)
works fine, and that Microsoft or Windows Update will update the FTDI-based
device drivers. You might have to use the "Custom" button on Microsoft
Update to have it examine device drivers versions.
