Right after sending this message, I recalled that I used powertop to do "auto tuning". Sure enough, one of the lines was this: Good Autosuspend for USB device UHCI Host Controller [usb6] By disabling it, it runs this command: echo on > /sys/bus/usb/devices/usb6/power/control And it resolves my suspend issues on 4.20.3-gnu. What sucks even more is that I had disabled those settings on the USB controllers over a year ago (because it was putting my USB keyboard to sleep, dropping the first keypress); don't know how it got re-enabled, but the user is probably to blame. Sorry for the noise, everyone. I hope that my suffering provides some value to others.
