USB 3 regression about mbp-2016-linux HOT 7 OPEN

For me the problem with devices after booting required running sudo lsusb -v

from mbp-2016-linux.

I am also on a 14,3. I boot from a usb3 drive and suddenly couldn't boot anymore (no crypto drive found). Thanks for localising this!

Are your devices detected after running the following script?

#!/bin/bash

for i in /sys/bus/usb/devices/usb*
do
  echo "on" > "$i/power/control"
done

Indeed this helps, at least for devices plugged in after boot. And so does usbcore.autosuspend=-1 . I am going to test if this also makes my boot hard disk work without reverting the mentioned kernel patch.

Yeah disabling autosuspend also fixes boot time device detection with modern kernels. Any idea how to make autosuspend work again?

In the "bad" state the USB port is powered though. Attached hard disks spin up, but aren't detected. The power setting of the device itself doesn't seem to matter, I think it is some hub that matters. If I run your script before attaching the device the device is detected fine when it is attached later.

It works for me on 13,1

from mbp-2016-linux.

ive got the same problem. i was able to get sudo lsusb -v to work once but it doesn't do it anymore. if i leave the usb drive connected and reboot the laptop, it works until the device is removed and re-inserted and then it never detects again until a reboot. have tried a few options for power cycling usb hub devices, etc but can't find anything that works. did anyone ever find a fix for this regression?

the only way i have found to work around it so far is to disable usb autosuspend but obviously this isn't a proper fix, it will lead to poor battery life, etc.
