[Bug 1857891] Re: Authentication code required for keyboardless device

** Description changed:

  Hi,
  
  I'm trying to connect a turn page pedal which acts partly as a two-
  button mouse (provides left- and right-click depending on the pedal you
  press) and partly as a keyboard (can send keycodes as enter, space,
  left, right, PgUp or PgDn...).
  
  It only has two pedals and no keyboard (see it on manufacturer's site:
  https://www.donnerdeal.com/products/donner-bluetooth-page-turner-pedal-
  for-tablets-ipad-rechargeable-black?_pos=4&_sid=b8e2efbcf&_ss=r).
  
  Whenever I try to connect it to bluez, it asks me for an authentication
  code which is impossible to provide, of course.
  
  I've search deeply but couldn't find any means to automatically "trust"
  my pedal.
  
  I've tried it on Windows and Android: it functions smoothly...
  
  Thank you in advance
