1-Wire with USB master broken in kernel version 5.10? #1753

Closed EvTheFuture closed 2 years ago

EvTheFuture commented 2 years ago

Describe the issue you are experiencing

Trying to setup 1-wire sensors using an Intel nuc and a DS9490R USB adapter.

The devices show up under /sys/bus/w1/devices but the w1_slave file is missing as well as temperature.

In Home Assistent the sensors show up but the state is set to "unknown".

Tried this on kernel 5.14 on a laptop and it works fine. If I boot the same laptop with kernel version 5.11 the w1_slave file is missing and I can't read any temperature data from the attached sensors.

I found this information which indicate that this issue has been fixed in kernel version 5.12 and later.

Are there any plans for bumping the kernel version any time soon?

What operating system image do you use?

generic-x86-64 (Generic UEFI capable x86-64 systems)

What version of Home Assistant Operating System is installed?

7.4

Did you upgrade the Operating System.

Yes

Steps to reproduce the issue

  1. Attach a DS9490 USB 1-wire adapter
  2. Attach at least one 1-wire sensor
  3. Try to read any data from the sensor

Anything in the Supervisor logs that might be useful for us?

Hm, yeah looks like a problem in 5.10 (and hence HAOS 6.x/7.x). I plan to update to the latest LTS kernel 5.15 for 8.x. I let you know once development builds for testing are available.

I let you know once development builds for testing are available.

Perfect, do you know an approximate time for when those builds can start to show up?

Is there anything I can do to help?

There hasn't been any activity on this issue recently. To keep our backlog manageable we have to clean old issues, as many of them have already been resolved with the latest updates. Please make sure to update to the latest Home Assistant OS version and check if that solves the issue. Let us know if that works for you by adding a comment 👍 This issue has now been marked as stale and will be closed if no further activity occurs. Thank you for your contributions.
