I think jailbait is right, and uteck led to the discovery.
Booting to a live ISO (tried various distros), I get the same results: no 3.0 ports work, and the very same xhci -110 error shows at bootup. BUT, this led me to find some strange behavior, which indicates that the 3.0 ports
are not actually dead, but may have some sort of physical issue.
Plugging a thumbdrive in a 2.0 port works as expected, every time.
Plugging a thumbrive into a 3.0 port will do some strange things:
Most of the time, the 3.0 ports act dead and there's no thumbdrive flashes.
Occasionally, I'll get a single flash right after hitting the power button/restarting.
Once, it flashed like crazy after POST, like the BIOS is trying to read it so it could add it to the list of boot options....but just it just flashed and flashed while getting stuck at the "Dell" boot image but didn't get any further.
Once,
it actually WORKED!!! BIOS recognized it as a boot device, and I was able to boot into the live ISO from a 3.0 port!
That gives me hope that I can take this laptop apart and find some sort of connection issue and restore USB 3.0.
It kinda makes sense why the ports consistently act dead once the OS gets the host controller error and disables it, but still does this erratic strange stuff pre-handoff to the OS.
It also confuses me, because I simply shut the computer down to physically move the location of one of the external HDD enclosures, and the problem started the very next time I cold-start the computer. I did NOT unplug anything from the laptop/docking station during the move.....just the HDD enclosure itself (which still works fine plugged into a 2.0 port now). The only part of the laptop/docking station that was touched or moved in any way was the power button to start it up when I was done moving the HDD enclosure. Very strange conditions for an internal connection issue to manifest for the first time.
I think I'm going to count this as a good-enough diagnosis, and possible solution. Thank you for the help!!!
Everything below is just for the sake of completeness. Read it, or don't. Not critical.
Power Details:
Every USB device plugged in has its' own power source except the keyboard and mouse, which have always been plugged into 2.0 ports, and I can't imagine either of those "straining" the USB power bus in the first place. I've swapped them out with different ones anyways just for good measure.
There was no power loss, or disconnected power cable at any point. I did a proper shutdown, and pushed the power button to bring it back to life. That's it.
Battery was changed in 2020 to a name-brand, high-quality, larger capacity one.
I've always kept the "Dell Rapid-Charge" BIOS feature disabled to maximize battery life with a standard charge rate for the 8 or so years that I've had this thing.
I have 3 working chargers (two 65W, and a 90W), and it's the same issue with all 3 chargers. I'm sticking with the 90W just for good measure.
BIOS Diagnostics reports the battery health at 100% and all 3 chargers "Pass" health checks. Same result whether fed it's through the docking station, or directly to the laptop.
