Hi, since last week I am seeing these and not sure how to fix it. I am running Ubuntu 18.04LTS and running plex
in docker
* today at 13:10:14 Starting Plex Media Server.
* today at 13:10:27 Critical: libusb_init failed
Thanks

Same, Seen this in unraid/docker version of plex as well.
What you’re seeing is the Plex Tuner Server attempting to initialize the USB to look for USB tuners.
If you have no USB tuners, ignore it.
If you do have USB tuners, and they’re not working, the first place to look is to make sure the host has udev
running to set the permissions so the Plex user GID can access it. What you’re looking for is having the GID be a member of the group which owns the USB devices (if you need it – else ignore it )

Hi @ChuckPa thank you so much for looking into this.
I use HDHomeRun over the network without any USB. So I will ignore this message.
But I never seen this message before. Is this something can be disappear in future releases as its not relevant to my setup?
Thanks
There is no way to know if your host OS will address the issue.
Either way, if you use an ethernet tuner – you can ignore if.
Thanks @ChuckPa for clearing the confusion.
Much appreciated.
Interesting. I’m seeing the same problem this morning. I do not have any tuner.
Running PlexMediaServer in Docker on UnRaid 6.9.2 I can no longer access the WebUI. It just sits and spins.
Hello, I’m pretty new to linux and I don’t know how to use udev. Can you explain how to set the permissions with udev for the plex user please ?
@CrazyCamel
If the udev package is installed, which most distros do by default,
then the package does the rest.
It either sets rules in the udev module for access to the hardware
-or-
Joins the group which owns the QSV video hardware (render or video)
If you do not have /dev/dri
, then the platform is not HW capable
Here is my docker-compose file :
version: "3"
services:
plex:
image: ghcr.io/linuxserver/plex:latest
container_name: plex
network_mode: host
environment:
- PUID=1000
- PGID=1000
- VERSION=latest
- PLEX_CLAIM= #optional
volumes:
- /mnt/drive/plex/config:/config
- /mnt/drive/plex/Series:/tv
- /mnt/drive/plex/Films:/movies
restart: unless-stopped
I’m also in the video group and I have /dev/dri
pi@raspberrypi:/dev/dri $ id
uid=1000(pi) gid=1000(pi) groupes=1000(pi),4(adm),20(dialout),24(cdrom),27(sudo),29(audio),44(video),46(plugdev),60(games),100(users),105(input),109(netdev),117(lpadmin),995(docker),997(gpio),998(i2c),999(spi)
Raspberry Pi devices have no Plex hardware transcoding support.
The Pi is not an Intel QSV capable cpu nor does it have an Nvidia GPU
