Created attachment 123398
  --> https://bugs.freedesktop.org/attachment.cgi?id=123398&action=edit
command lines and their output for my distro, and various device profiling and
some logs

I'm getting the below "PreInit returned 2" error when I plugin my keyboard
(showing up as "Gaming Keyboard". FWIW I don't think there's anything special
about the keyboard; this is the device: http://amzn.com/B00T1P6F1S):

  May  1 18:01:39 carboy /usr/lib/gdm3/gdm-x-session[1504]: (II) failed to
create input device '/dev/input/event7'.
  May  1 18:01:39 carboy /usr/lib/gdm3/gdm-x-session[1504]: (EE) libinput:
Gaming Keyboard: Failed to create a device for /dev/input/event7
  May  1 18:01:39 carboy /usr/lib/gdm3/gdm-x-session[1504]: (EE) PreInit
returned 2 for "Gaming Keyboard"
  May  1 18:01:39 carboy /usr/lib/gdm3/gdm-x-session[1504]: (II) UnloadModule:
"libinput"

(a more full /var/log/syslog output is attached, from time I plugged in the
keyboard)

:: Debugging/system specific info:

My output from `xinput list` `lsusb` before and after plugging in (with a `tail
-f /var/log/syslog` in between):
  attached as "SystemInfo_kernel_distro_xinput-list_lsusb_logs.txt"


Pasting inline, installed packages and their versions (just `grep`ed for

Let me know how I can further debug this. I take it from these
https://wayland.freedesktop.org/libinput/doc/latest/reporting_bugs.html
instructions that `evemu` doesn't apply here, since I don't have an event node
that hangs around to begin with.
