Net::SSH:Perl can't login SSH1 - perl

Question

I'm trying to connect me to a switch using SSH1 (the switch is old and does not support ssh2) and after the firsts steps, my program dosen't do nothing and i have to Ctrl+C to stop it
# Perl v5.8.8 built for MSWin32-x86-multi-thread
#!perl
use strict;
use warnings;
use Net::SSH::Perl;
my $host = "10.*.*.*";
my $username = "***";
my $password = "***";
my $cmd = 'show version';
my $ssh = Net::SSH::Perl->new($host, debug => 1);
$ssh->login($username, $password);
my($stdout, $stderr, $exit) = $ssh->cmd($cmd); #the script stops here
print $stdout;
logs :

i can log me in with putty and it works.
I used wiresharck and we can see that the password and maybe the login are not used counter to putty http://image.noelshack.com/fichiers/2016/31/1470038197-troubleshooting2-ssh1.png, packets are too lights.
I don't understand what's going wrong, why the connection failed and logs say nothing about it.

It seems that it's a problem about my 3 HP switch (2524,5304, 5130). I finally tested on a cisco switch and it works perfeclty........
I will search a solution in they key size or something like that
Edit : i'm using python now and its the same problem but i found the solution here http://forums.juniper.net/t5/ScreenOS-Firewalls-NOT-SRX/Python-Paramiko-with-netscreen/m-p/294864
