Hello

I'm install Device::USB from apt-get on my Ubuntu machine. I have usb device. With wireshark i get protocol from anower software. The protocol used to communicate bulktransfer

but when i try implement it with Device::USB i have no luck 

#!/usr/bin/perl -w
use strict; 
use Device::USB;

    my $usb = Device::USB->new();
    my $dev = $usb->find_device( 0x2642,0x0669);

    printf "Device: %04X:%04X\n", $dev->idVendor(), $dev->idProduct();

    $dev->open ();
    $dev->claim_interface();
        $dev->set_configuration (0);

my $cmd = $dev->{config}->[0]->{interfaces}->[0]->[0]->{endpoints}->[0
+]->{bEndpointAddress};
my $string = $dev->{config}->[0]->{interfaces}->[0]->[0]->{endpoints}-
+>[1]->{bEndpointAddress};
my $data = $dev->{config}->[0]->{interfaces}->[0]->[0]->{endpoints}->[
+3]->{bEndpointAddress};

my $send = $dev->bulk_write($cmd,hex('dd'),1000);
my $data;
my $read = $dev->bulk_read($string,$data,64,1000);
$read = $dev->bulk_read($string,$data,64,1000);

I can't see any output in wireshark. And i have $send =-1 and read='-1'

What i'm missing ?

PS sorry for English
