I've found the USB and CODEC drivers in Windows 10 Pro {latest update}
to be quite stable and reliable. I have 2 physical USB ports on this HP
laptop computer which I use for my radio applications. The 3rd USB
port is always used for my wireless mouse. I can use either one with
the K3S and WSJT-x always loads and connects correctly to the previously
assigned port in the WSJT-X F2 Setup menu. In my case the K3S always
comes up on Port 5 and the audio comes up under USB CODEC. I have
not found it necessary to load any drivers nor have I found any drivers
deleated.
Even shutting things down, rebooting the computer, when I load WSJT-X
all comes up correct. Now......I am not using any other applications
associated with the radio such as logging, virtual ports, or USB Hubs.
In my thinking ......"more crap = more issues". Otherwise, KISS....
Now I will say if I use the computer to do some of my audio file
editing, playing back music, or other computer sound requirements,
sometimes using other ham radio applications such as FLDIGI, HRD, HDSDR,
and etc, I may have to set the defaults in the specific program again.
Same for audio levels for Recording Devices and Playback Devices. But I
don't find moving the USB cable from one port to another causes any issues.
Yes, Don is correct, if you are looking at Device Manager, have Ports
(COM & LPT) expanded you should see the USB Serial Port (COM #) come and
go as the USB cable it plugged in or the radio is turned off and on.
Same for the USB Audio CODEC under the Sound, Video, and Game controllers.

Yes, I understand that, Don. My point was that when the USB cables are plugged
in, something is changing or removing the drivers. One time everything works
OK and the drivers are there, next time it fails and the USB drivers are gone
or changed.

Lee,
As you discovered, when the USB cable is not plugged in, the USB Audio CODEC is
not shown in Device Manager. That is normal. Did I misread something?

I previously had a thread on problems I was having the internal sound card on
FT8. I was getting no output from the PC to the radio. So thinking that the
problem was how I had the internal sound card and WSJT-X set up, I switched
back to using my SignaLink, which had worked perfectly before. It worked fine
for a while, but then the failed output problem returned. Mysteriously, it
would start working again and then after a time fail again.
At one point I found that there were two USB Audio Codecs and the standard
Realtek driver associated with the speaker settings. I selected the one one
not then i use, and the output returned. Then after another failure, I found
that there was only one USB Audio Codec associated with the output.
