[Bug 1568621] Re: input-linux misdetects Logitech keyboard as a mouse

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.

If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.

Thank you and sorry for the inconvenience.

Title:
  input-linux misdetects Logitech keyboard as a mouse

Status in QEMU:
  Incomplete

Bug description:
  The new input-linux.c code misdetects my Logitech K350 keyboard as a
  mouse.  The bug is in the input_linux_complete function.  The evdev
  for this keyboard returns an "evtmap" with the EV_REL bit set.  Full
  evtmap is 0x0012001F.  Using a different keyboard everything works as
  intended, so my configuration and setup are correct otherwise.

  
  Suggestion:

  I suggest adding an object property called something like "type" where
  the user can specify what the device type is manually.  This K350
  keyboard shows that "evtmap" cannot be used to reliably detect the
  device type.  Since specifying the device type manually is not an
  undue burden, perhaps it should be a required option and there should
  be no autodetection?

  Arch linux, using qemu-git AUR package installed 20160409.
