Title:
  Logitech mouse LX5 ( 046D:C50E ) not well identified

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  I'm using a Logitech LX5 cordless optical mouse and is recognised (or seems to be) but get hard time using it:
  - single/double click give very erratic results
  - select & drag is a nightmare: often lost the selected object on the way, or need several tries before being able to select it
  - System Settings mouse options seems really useless

  Pluging that mouse with its os2 adaptor or directly on usb makes no
  difference.

  These issues are observed from 12.04  with its stoc kernel to 14.10
  with the latest kernel upstream. So i wonder if its only a kernel
  issue or a server config when compiling or the compiler itself.

  That said, the problem is serious and very annoying when , for
  example, i want to select large block of cells into libreoffice calc,
  as most of the time the selection is lost before having done the job.

  That is: that mouse only have 2 buttons and a wheel, but xorg.0.log warns about:
  Warning: Only changing the first 12 of 24 buttons.

  So i'm not sure which package has to be blamed:
  mousedev driver ? hardware identification ? xserver ?
