Re: keyboard/mouse at dock not working anymore after update

Did you actually check that at some point?

yes. There aren't really too many options on a Thinkpad this old. I changed all the USB and charging modes I have, some Wake on Lan via Dock, disabled Wake by Thunderbolt and disabled Thunderbolt and USB devices in Pre Boot Enviornment. I tried it with AC connected and disconnected, still no joy in any constellation

You could also try the arch installation iso and the dock on the other notebook and a live version of Pop!OS on the currently affected one…

I trued the Pop_OS iso with the bad laptop, but it did not work. But then my working laptop obviously has seen some updates over the years, to the 22.04 LTS is not in its vanilla state anymore.

But these Thunderbolt controllers have their FW too and I wouldn't be surprised if it's a separate flash chip which can be updated separately. And the dock may have FW.

The dock for sure has FW, as I updated it in the past.

IMO there are three viable approaches:
0. If you haven't already, try a "full power cycle": disconnect all power sources and the battery for a minute. Technically there is likely still an RTC battery, but hopefully it isn't used to maintain any state in the TBT controller.

did that, did not change anything

1. Check if the "HC died" is triggered by powering root hub ports on or merely a coincidence.

How would I do that?

Does the arch install iso work w/ the dock on the other laptop?

How would I do that?

I assume the idea is just to

echo 'on' | sudo tee /sys/bus/usb/devices/usbX/power/control

for the relevant usbX
