Hi, can you switch to "auto" with powertop? If not, it's a kernel driver or hardware issue. |
|
Yes, I can - I switched it in |
|
TLP handles USB devices with the help of udev events. I guess the kernel prevents writing Reboot and show the trace output: ps. on my X1C6 here (very similar hardware) with kernel 5.9 the reader device behaves as expected. |
|
I just remembered, since you use OpenSUSE: #537 Make shure the latest tlp package is installed, otherwise udev events won't work at all. |
|
Thank you. I put It switches from battery to AC mode and vice versa just fine, so I think #537 does not affect me. I use TLP 1.3.1 from the latest Tumbleweed package with kernel 5.9.1, so that should be fine. |

The trace reveals no udev events at all. Strange. Are there events in the trace when you (re)plug some USB device like your trackball? I suggest you try to change to USB batch mode by configuring: Reboot and show the trace again. |
|
I'm still missing your feedback on the workaround. |

Hi! Sorry for answering late, I had some work to do and it slipped my mind. I've put the line you suggested ( If I do a |

No. Here is the I currently have this in my Should there be more USB-related output visible? |

There should be a line for every USB plugin event. By now i am quite sure that either you have installed the defective package from #537 or there is something else wrong with your udev installation. Please show: |

I doubt it's the same issue as #537, because AC/BAT is working just fine, and that bug was fixed in the openSUSE repositories in October. But just in case here is the TLP version I'm using: Here's the And here's the output from |

Let's look at the full package contents then: I would also like to see: |

Sure. Here are the package contents: And the content of |

The install path /usr/lib/udev/tlp-usb-udev is fine. I dissected the .rpm myself and found that 85-tlp.rules and 85-tlp-rdw.rules contain the wrong path: The problem occurs when the package build calls TLP's Makefile with the TLP_ULIB parameter (tlp.spec Line 77): This should give TLP_ULIB=/usr/lib/udev but seems to produce /usr/libexec/udev instead. I suggest you file a bug against the openSUSE package. Btw, the same construct works in Fedora's tlp.spec. One more thing to add to your bug report: /usr/share/bash-completion/completions/tlp-rdw is installed by the tlp binary package although it belongs to tlp-rdw. |

Thank you. I've filed bug 1180495 against openSUSE tw for the path in the udev rules, and bug 1180496 for the bash completions in the wrong package. |

Great, let's see. |

openSUSE has a new version of the tlp package (1.3.1-3.1) that shows udev events in the The card reader is shown with |

Describe the bug
My notebook (Lenovo Thinkpad X1 Yoga 3rd gen) has a built-in Realtek USB3 MicroSD card reader (USB ID
0bda:0328) that I never use. My system is on OpenSUSE Tumbleweed.TLP reports the card reader as
control=on. In order to enable autosuspend on the card reader, I have whitelisted it withUSB_WHITELIST="0bda:0328"in my/etc/tlp.conf. Nevertheless,tlp-statstill shows the reader ascontrol=on.Expected behavior
tlp-statshould show the reader ascontrol=autoTo Reproduce
The behaviour is the same on AC and battery power.
Steps to reproduce:
USB_WHITELIST="0bda:0328"in/etc/tlp.conftlp-stat, check for0bda:0328in the+++ USBsectionAdditional context
powertopalso reports the card reader, and the (empty)/dev/sdbdevice attached to it, as "Bad" with autosuspend disabled.The text was updated successfully, but these errors were encountered:
