JT,
You may want to consider changing the PTT keying to the USB adapter even
though your current setup 'is not broke'. The reason is that the PTT
keying is a rather simplistic task requiring that the adapter correctly
implement only RTS and DTR signals, and the timing is not really
critical either.
For rig control it can be a little more 'dicey' because there are
latency issues that the adapter can introduce as well as other problems
in that some adapters work well while others do not. OTOH, if you are
also using the serial port for CW keying, then an adapter may not work
very well for that either because of the latency problems introduced in
the computer/OS/adapter combination.
In either case, try to use the USB connection native to your computer
rather than a USB hub. This is computer/usb hub dependent, but the
chances of an adapter working properly are much better when plugged
directly into the computer.
There is alway the new Elecraft USB to serial adapter that is being
offered as an accessory for the K3 - at least you know it has been
tested for rig control operation.

USB to serial adapters are a dime a dozen and not all chipsets in them

the KIO2 interface? If so, which brand and model are you using?
My single serial port is currently being used for PTT keying for data
modes and it's not broke so I don't want to fix it. *grin* I'd also
rather not tie up my last PCI slot with a dual port serial adapter.
Thanks
