USB device is not detected during boot, again

[Jarkko Toivonen]

I have an ethernet adapter (ASIX Electronics Corp. AX88179 Gigabit Ethernet) attached to a USB-C port of my laptop. After update to kernel 5.4.0-90-generic it stopped working again. Same problem with 5.4.0-91-generic. Detaching and reattaching the adapter doesn't help, but after suspend and resume it starts working again, until the next boot. I had the same problem earlier and it was fixed here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1939638 , but the bug got reintroduced in kernel 5.4.0-90-generic most likely due to this patch:

* Fix cold plugged USB device on certain PCIe USB cards (LP: #1945211)
 - Revert "UBUNTU: SAUCE: Revert "usb: core: reduce power-on-good delay time of
      root hub""

I'm running Ubuntu 20.04. USB2 ports work without problems.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This change was made by a bot.

Please test latest mainline kernel:
https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16-rc5/amd64/

Headers are not needed.

[Kai-Heng Feng (kaihengfeng)]

If mainline kernel doesn't work, I am working on a similar case that may help your case too.

[Jarkko Toivonen (jttoivon)]

I downloaded the following packages:
linux-image-unsigned-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb
linux-modules-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb

And installed them with sudo dpkg -i linux-image-unsigned-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb linux-modules-5.16.0-051600rc5-generic_5.16.0-051600rc5.202112121931_amd64.deb

While trying to boot it, it stopped after "Loading initial ramdisk...". It didn't respond to keys in any way. I read that proprietary drivers (nvidia) could cause problems, so I selected Nouveau instead of nvidia from "Software & updates" -> "Additional drivers". This removed the nvidia-driver-460 package. Then I reinstalled the mainline kernel. But still it wouldn't go any further in the boot. (Kernels 5.4.0-89 and 5.11.0-36 still booted.)

Am I doing something wrong or is the problem in the kernel?

[Kai-Heng Feng (kaihengfeng)]

Try kernel parameter "nomodeset".

[Jarkko Toivonen (jttoivon)]

That did not help either. I also tried rc6, but the results was the same. No output even when quiet and splash kernel parameters were removed.

[Jarkko Toivonen (jttoivon)]

I tried rc7, but it doesn't boot either.

Just to make sure I'm not doing anything wrong, I installed the mainline kernel 5.15.11. It booted fine, even without nomodeset. And my USB net adapter seems to be working. At least in the two reboots that I tried. The 5.15.11 version seems to include your commit "xhci: Remove CONFIG_USB_DEFAULT_PERSIST to prevent xHCI from
runtime suspending", and the (previously) problematic part in drivers/usb/core/hub.h:
 if (!hub->hdev->parent) /* root hub */
  return delay;
 else /* Wait at least 100 msec for power to become stable */
  return max(delay, 100U);

So, this could fix the problem, but I guess I have to wait until the Ubuntu version of the 5.4.x kernel.

[Jarkko Toivonen (jttoivon)]

The 5.16-rc7 did boot when I gave the acpi=off parameter. The nomodeset parameter was not required. The network stick worked. But due to acpi being off, only one cpu was detected.

[Jarkko Toivonen (jttoivon)]

In the kernel 5.4.0-96 it worked randomly. I noticed that instead of the suspend/resume cycle, it was enough to run 'sudo lsusb -v'. After this the USB net stick was detected. Note that both 'sudo' and '-v' were required to have an effect.

Version 5.4.0-97 (still in proposed state) has a proper fix:
Focal update: v5.4.160 upstream stable release (LP: #1953387)
xhci: Fix USB 3.1 enumeration issues by increasing roothub power-on-good delay

Looks like it took two months for this patch to come from mainline kernel to Ubuntu kernel.
