“The 62-nut-usbups.rules file looks pretty standard. Do you know if the changes to 42-usb-hd-pm.rules are needed? It seems like none of the USB devices would have the right permissions if 62-nut-usbups.rules isn't sufficient (though this happened in Debian once).”
My means of testing wasn’t the most rigorous, but I did try to use variable isolation with these changes and some other changes. I could not make the drops stop without having all 3 of these changes present. I believe a web search lead me to this udev rule so I’ll dig up the link for context.

I think you mentioned the CentOS version - which kernel version does that run? ("uname -r" is probably sufficient)

<p>CentOS 7x uses RedHat's idea of 3.10.0 .. which means it's a
heavily patched 3.10. And by heavily I mean that in the 4 years
since RHEL 7 was released, they added tons ( literally thousands )
of backports from 4.xx, including from 4.18</p>
<p>Latest available kernel in the CentOS 7.6 line is 3.10.0-957.21.2
but today we will probably release 3.10.0-957.21.3 which includes
the fix for TCP SACK.<br>
</p>
<p>The public beta of RHEL 7.7 uses 3.10.0-1049 but 7.7 GA will
certainly use a newer release. I have already in use a beta of
3.10.0-1055</p>
