My SteamVR just doesn't seem to be able to connect to the headset. The USB devices are present (and the entire package works on dual-boot Windows), but SteamVR on Linux reports that it can't open the USB devices.

It looks a bit like a permissions issue, but I've checked and double-checked everything and believe mu configuration to be correct. Normal system users should be able to access the Vive.

Your system information

  • Steam client version (build number or date): Jun 21 2017
  • Distribution (e.g. Ubuntu): Gentoo (stable)
  • Graphics driver version (run nvidia-settings): NVidia proprietary 381.22
  • Gist for SteamVR System Information: https://gist.github.com/Cygon/1690eb31a04cd571cb33fdcbc2ef6418
  • Opted into Steam client beta?: Yes
  • Opted into SteamVR beta?: Yes
  • Have you checked for system updates?: Yes
  • Display Configuration: 1 DP, 1 DVI, 1 DP->DVI, 1 HDMI (Vive)

Please describe your issue in as much detail as possible:

SteamVR works fine on Windows. When I run SteamVR on Linux, it reports "Headset not detected."

I have set up user access rules to udev as requested in https://github.com/ValveSoftware/SteamVR-for-Linux#usb-device-requirements

Furthermore, my user is a member of the "usb" group, "video" group and "input" group.

Doing an lsusb under my normal user account gives me:

Note that Gentoo uses OpenRC rather than systemd and that I'm running Steam on KDE rather than GNOME.

Steps for reproducing this issue:

  1. Connect HTV Vive to a Gentoo Linux system
  2. Install Steam + SteamVR
  3. Set up udev rules
  4. Launch SteamVR

Okay, it was a systemd problem. I'll forego the stream of swears about this init system (an ACL named "uaccess" that I'm supposed to know is for USB devices and that's assigned via the TAG statement?), hope that it will die a quick death and provide a solution myself:

If your system is running OpenRC, instead of tagging the USB device nodes, use normal UNIX access rights:

# HTC Vive HID Sensor naming and permissioning
KERNEL=="hidraw*", SUBSYSTEM=="hidraw", ATTRS{idVendor}=="0bb4", ATTRS{idProduct}=="2c87", MODE="0666", GROUP="usb"

SUBSYSTEM=="usb", ATTRS{idVendor}=="114d", ATTRS{idProduct}=="8a12", MODE="0666", GROUP="usb"`

The HTC Vive will then be found by Steam and fail to initialize because the bluetooth driver for waking up the base stations doesn't install.

CChristophHaag 2017-10-22 github

There is no special bluetooth driver. It's a standard broadcom bluetooth chip that only needs an usb id entry in the kernel to make the broadcom kernel driver use it. It's in the kernel since 4.11: https://github.com/torvalds/linux/commit/a57bac43468e005064d6560183b313b269403f0a

It's SteamVR on Linux that does not implement any bluetooth functionality.

There has been some reverse engineering at https://github.com/nairol/LighthouseRedox/blob/master/docs/Base Station.md#bluetooth-le-communications but it's not all complete (with firmware updates etc)

@Cygon Do you have sys-apps/usbutils installed? I recall having a similar problem until I installed sys-apps/usbutils.

CCygon 2018-10-04 github

@ryao I honestly don't remember if I had it installed when I had this issue a year ago.

My issue was solved when I translated the systemd udev rules into OpenRC udev rules, maybe usbutils is needed on top of that, maybe it isn't :)

Nothing extracted yet.
