I think the telnet#login method is waiting for the text "login" and
therefore cannot catch the "Username" text prompt.

Try using #waitfor...

Eg,

--------------------------------
>cat ttest.rb
# test using waitfor

time_start = Time::new

require 'net/telnet'
host = "10.1.1.1"
tn = Net::Telnet::new( \
           "Host"       => host,         # default: "localhost"
           "Port"       => 23,           # default: 23
           "Binmode"    => false,        # default: false
           "Output_log" => "output_log", # default: nil (no output)
           "Dump_log"   => "dump_log",   # default: nil (no output)
           "Prompt"     => /[$%#>]/,     # default: /[$%#>] \z/n
           "Telnetmode" => true,         # default: true
           "Timeout"    => 5,            # default: 10
           "Waittime"   => 0             # default: 0
)
tn.waitfor(/ogin:/) {|c| print c}   

#            ^   in your case, 
#------------^   replace this w "tn.waitfor(/username/) {|c| print c}"
#

tn.puts "test"
tn.waitfor(/assword/) {|c| print c}
tn.puts "test's password"
tn.cmd("uname -an") { |c| print c }
tn.cmd("ls -la") { |c| print c }
tn.cmd("exit") {|c| print c}
tn.close

puts
puts "#{Time.now - time_start} seconds"
