[Bug 1222763] Re: Pressing usb keyboard multimedia keys doesn't print anything with sudo /lib/udev/keymap -i input/eventX

 

I've tried the keyboard without the ps2->usb adapter on lubuntu 12.10
(desktop pc). In this case, multimedia keys are recognized both by sudo
/lib/udev/keymap -i input/eventX and by sudo evtest commands.

This is really strange because the multimedia keys work well even using
the ps2->usb adapter (though they do not print anything with keymap and
evtest commands).

What may be due to this bug (which does not allow debugging on the
computers without ps2 ports)?

Title:
  Pressing usb keyboard multimedia keys doesn't print anything with sudo
  /lib/udev/keymap -i input/eventX

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I've got a multimedia wireless keyboard. When I try to type:

  /lib/udev/findkeyboards

  I get:

  USB keyboard: input/event4
  AT keyboard: input/event3

  Then, if I type:

  sudo /lib/udev/keymap -i input/event4

  pressing the multimedia keys print nothing in the command output
  (while the standard keys print output as expected. Example:
  scan code: 0x70018   key code: u).

  I'm using the 3.2.0-41-generic kernel with Lubuntu 12.04, but this
  problem is present also in other kernel versions.

  The udevadm info --export-db (with connected and not connected
  keyboard) output and the diff command output are attached to this bug
  report.
