use Device::USB;

    my $usb = Device::USB->new();
    my $dev = $usb->find_device( $VENDOR, $PRODUCT );

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

    my $cfg = $dev->config()->[0];
    my $inter = $cfg->interfaces()->[0]->[0];
    print "Interface:", $inter->bInterfaceNumber(),
       " name: ", $dev->get_string_simple($iter->iInterface()), 
       ": endpoint count: ", $inter->nNumEndpoints(), "\n";
