Thanks again, Michael Potter
I saw that 4.3.3-5 landed in Testing, so I upgraded. After the reboot,
there were no more xhci error messages. The adapter shows up just fine
in plasma-nm, and I ran a few speed tests to generate traffic.
Everything's looking good, and it seems like this update fixed the problem.
