device: proper handling of user input

Browse source 
(1) If the user denies something on the Ledger,
    a proper error message is now shown.
(2) Ledger doesn't time out anymore while waiting
    on user input.
(3) Lower the timeout to 2 seconds, this is enough for
    normal Ledger <-> System communication.
