The serial line exists for this USB stick, but the udev rule still isn't
picking it up:
  Device = "1-3.2"
  Device path = "/sys/devices/pci0000:00/0000:00:1a.7/usb1/1-3/1-3.2"
    authorized          = "1"
    bConfigurationValue = "1"
    bDeviceClass        = "00"
    bDeviceProtocol     = "00"
    bDeviceSubClass     = "00"
    bMaxPacketSize0     = "64"
    bMaxPower           = "200mA"
    bNumConfigurations  = "1"
    bNumInterfaces      = " 1"
    bcdDevice           = "4000"
    bmAttributes        = "80"
    busnum              = "1"
    configuration       =
    descriptors         = ""
    dev                 = "189:6"
    devnum              = "7"
    idProduct           = "0098"
    idVendor            = "0411"
    manufacturer        = "BUFFALO"
    maxchild            = "0"
    product             = "USB Flash Disk"
