Ubuntu 13.04, USB3-HUB7-81X, and xhci_hcd errors


#1

I am having problems with Ubuntu 13.04 and a USB3-HUB7-81X Plugable USB hub. When I plug it in, I get strange behavior reported in dmesg:

And that’s with nothing plugged into the hub:

If I try putting things on the hub, I get more frequent resets, leading to glitches in whatever USB devices I have plugged into the hub (e.g., lost keystrokes if I have a keyboard plugged in).

Any suggestions?

Thanks!

Hello,

Thank you for contacting Plugable support! I’d be more than happy to assist you with this issue with your hub.

First take a look here:

http://plugable.com/2013/06/07/troubl…

Specifically at the sections on “Ensure the hub operates in “Self-Powered” Mode” and “For issues specific to ports 1-4, apply firmware version 8581”.

The hub might not be in self powered mode which can cause strange issues, also the firmware might need to be updated from a Windows environment.

For further questions please email us at support@plugable.com

Thanks again for contacting Plugable support and best wishes!

“Ensure the hub operates in “Self-Powered” Mode” had all been done prior to my posting here.

With regards to “For issues specific to ports 1-4, apply firmware version 8581”, as wrote earlier, “that’s with nothing plugged into the hub”. This means that there is nothing plugged into ports 1-4. Yet, just with upstream plugged into the notebook (Dell XPS 15, L502X), I get the errors noted.

Hello,

If possible I would still try to see if the firmware is out of date if you have access to a Windows machine.

For further questions please email us at support@plugable.com

I have applied the update using a Windows machine. The symptoms are unchanged.

Note that the error messages occur on either of the two USB 3.0 ports available on this L502X.

Hello,

  1. Can you try the hub on a USB 2.0 port and see if these errors occur?
  2. What USB 3.0 controller chipset does your computer have?

Thanks again for contacting Plugable support and best wishes!

> Can you try the hub on a USB 2.0 port and see if these errors occur?

I get different errors:

(one message about every 3-4 seconds)

> What USB 3.0 controller chipset does your computer have?

I can tell you that lspci -v reports the following USB entries:

#8

Hello,

It is possible the issue has to do with the selective suspend timeout length for the system’s host controller.

Try entering in the terminal:

echo -1 >/sys/module/usbcore/parameters/autosuspend

No effect; the same error messages appear, including a reset of the hub.
