[Bug 1337641] [NEW] Oculus Rift "drifts" on recent kernels

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

When running Oculus Rift compatible software, the HMD rotation seen by
software drifts by a few degrees per second, even when the HMD is not
moving at all (ie, it's sitting perfectly still on the desk).

This is a regression in 3.13.0-27 and newer. Downgrading to 3.13.0-24
prevents the bug from happening.

The bug happens after using the OR in hidraw mode (which is what the OVR
SDK uses), and will even persist if you reboot into Windows without
power cycling the device.

OpenHMD is an alternative SDK for the Oculus Rift. When using OpenHMD in
libusb mode the problem does not happen, unless you have previously used
some software which opens the OR in hidraw mode. OpenHMD can also be
compiled to use hidraw, and if you do that it just shows a black screen
with the example. If you then run it in libusb mode, the drift happens.

This bug has been reported on the Oculus forums:

To me this looks like a HID bug. Something is messing up the state of
the hardware so badly that it will continue to report bad data even when
using software that works correctly after a power cycle. Looking at the
commits between -24 and -27 kernels I see a bunch of commits to HID
which look like they might be responsible for this.
