the hp phrasebook as shipped contains the prompt 'basic', which
overlaps and conflicts with the pass(word) prompt (which is inherited from
the cisco pb). (as far as i can tell from reading the source
of n::a::s and n::c::i, prompt basic isn't even used anywhere?)
that prompt basic matches on /: ?$/ causes n::a::s to fail logging
in on hp procurve devices because the device requests the password
with "username's password: " and basic catches that before the pass(word)
prompt can fire. see the following debug snippet:

and the password is never sent and the session eventually fails
with "login failed to remote host - prompt does not match"
