I believe the spots you see are when the radio was connected to my older laptop. I've attached a diagram of how I have things physically configured. To move between the old and new laptop is a matter of moving the cable connected to the USB hub's host port. I've attached a diagram.
The failure is always the same - when I move the hub's host cable to the new laptop, I can see that I'm transmitting the full 10 watts which I've configured the radio for but nobody answers and PSKReporter never shows that any stations have spotted my transmissions. When I connect the hub's host cable to the old laptop and run WSJT-X, many stations spot my transmissions and I complete QSO's.
When the storms in my area have moved out, I think I'll try a different mode besides FT8. I think I'll also install fldigi and see how it does. I might send some cw as well. I'll report my findings.
Thanks again Mike! By the way, I don't want anyone to spend an inordinate amount of time on this, I can continue to use the old laptop.

When you say "TX still failed" what does that mean? No power out? Or power out but nobody answering you?
I show you being spotted 18 hours ago so you apparently got TX working for a while.

Tim, I haven't set the radio in split mode. For a test I tried setting
it to split and made sure both VFO's were set to the same frequency.
WSJT-X still decoded and in fact would decode even as I switched back
and forth between VFO's. Alas, TX still failed in that config.
At this point I'm led to believe that either I'm not sending ft8 or if I
am it's something like a USB/LSB or frequency issue. I'll see if Mike
Black sees anything or not. Maybe I'm stuck using the older laptop for

Unless I am mixing messages in my head, the Hamlib error looked like you were using split? If so, is the *second* VFO also set for USB? If not, you may be transmitting LSB, or ??? which will not be heard. As a test (and if you are running split), try setting split to "None" and retest . . . that way, if you are decoding, you know that the mode is set correctly, and can work the issue from there.

Hmm, lots of info here, not sure how much I can help, but a few observations:

WSJT-X (running on Linux) running with my KX3 receives and decodes FT8 fine but no transmissions ever show up on PSKREPORTER. WSJT-X can change bands and follows the frequency if I manually change it. When transmitting I see my radio's TX light come on and the RF indicator shows that it's transmitting.
I have set my Elecraft KX3 to output 10 watts. The SWR shown on the radio is about 1.1 - 1
and the RF indicator shows 10 so I believe I'm transmitting the 10 watts on 14.074 MHz
Unless your small SW transistor radi is receiving USB at exactly 14.074 MHz, you may not hear anything, so I suspect that's a red herring.
I held a small SW transistor radio tuned for it's 19M band next to coax feeding the antenna and I
hear static until tWSJT-X transmits and then I hear complete silence.
I'd upgrade hamlib as per Mike W9MDB's instructions and see if that helps.
I don't know if Linux is as helpful as Windows by adding equalization and echo cancellation, but you should be able to determine if that's the case.
I don't have an equalizer app installed on the new laptop but I could install one just to confirm that the audio is flat.
Wait, what's flucuating? Everything should be constant output, constant power, single tone from the 8 available, etc. If you can hear it, it's a distrinctive warble, look online for sample sounds.
When WSJT-X transmits I see the output device volume control fluctuate so I think sound out is set correctly.
