Logitech Precision Gamepad shows axis activity upon connection

[eddiewould]

When I connect my Logitech Precision Gamepad (or the machine starts up with it connected) it exhibits activity on both axes until I press a button/press the d-pad.

UPON PLUGGING USB CONNECTOR IN:
===============================
Driver version is 2.1.0.
Joystick (Logitech Logitech(R) Precision(TM) Gamepad) has 2 axes (X, Y)
and 10 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4).
Testing ... (interrupt to exit)
Axes: 0:-32767 1:-32767 Buttons: 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off 8:off 9:off

AFTER PRESSING ANY BUTTON OR THE D-PAD:
=======================================
Driver version is 2.1.0.
Joystick (Logitech Logitech(R) Precision(TM) Gamepad) has 2 axes (X, Y)
and 10 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4).
Testing ... (interrupt to exit)
Axes: 0: 0 1: 0 Buttons: 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off 8:off 9:off

EXPECTED BEHAVIOUR:
===================
Both axes (0 & 1) should be "at rest" (i.e. 0, not +/- 32767) when the gamepad is initially plugged in.

Note - I'm not sure whether the d-pad should be classified as a pair of axes or a pair of hats - it is a digital d-pad though, *not* analog.

In case it's not clear, the excerpts shown are from running jstest /dev/input/js0

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.7 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hi,

I can't tell you whether the issue started after an update/upgrade sorry - I've only noticed it recently.

I've installed the 4.7 upstream kernel and the bug is still exhibited:
eddie@codey:~$ uname -a
Linux codey 4.7.0-040700-generic #201607241632 SMP Sun Jul 24 20:34:30 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
eddie@codey:~$ jstest /dev/input/js0
Driver version is 2.1.0.
Joystick (Logitech Logitech(R) Precision(TM) Gamepad) has 2 axes (X, Y)
and 10 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4).
Testing ... (interrupt to exit)
Axes: 0:-32767 1:-32767 Buttons: 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off 8:off 9:off

I've therefore tagged the issue "bug-exists-upstream" and marked it as confirmed.

[penalvch (penalvch)]

eddiewould, in order to keep this relevant to upstream, one would want to continue testing the latest mainline kernel (now 4.8-rc4) as they are released.

Could you please advise?

[eddiewould (eddie-eddiewould)]

Have re-tested on 4.8rc5, behaviour has not changed.

eddie@codey:~$ uname -a
Linux codey 4.8.0-040800rc5-generic #201609041832 SMP Sun Sep 4 22:34:01 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

Have changed bug back to "Confirmed".

[penalvch (penalvch)]

eddiewould, could you please plug the gamepad in, execute the following in a terminal and post the results here uncompressed/untarred:
usb-devices

[eddiewould (eddie-eddiewould)]

Please see attachment for usb-devices output.

[penalvch (penalvch)]

eddiewould, the issue you are reporting is an upstream one. Could you please report this problem following the instructions verbatim at https://wiki.ubuntu.com/Bugs/Upstream/kernel to the appropriate mailing list (TO Jiri Kosina and Benjamin Tissoires CC linux-usb)?

Please provide a direct URL to your post to the mailing list when it becomes available so that it may be tracked.

Thank you for your help.
