                          I have a USB speaker (a Jabra Speak 410 ) which I need to update the firmware on.  When I try to use fwupdmgr it sees the device, informs me of the _existing_ firmware version (1.9) but does not execute any updates:

    $ fwupdmgr get-devices
    Jabra SPEAK 410 USB
      DeviceId:             87caecc4e6db7e3c335deedfef38666e7f279a03
      Guid:                 537f7800-8529-5656-b2fa-b0901fe91696

      Flags:                updatable|registered
      VendorId:             USB:0x0B0E
      Version:              1.9
      Icon:                 drive-harddisk-usb

    $ fwupdmgr update
    $

I verified that there is an update file available (version 1.12 ).  When I download the update file (Jabra_SPEAK_410_USB-1-12-0.dfu) and attempt to use it with fwupdmgr write it doesn't seem to do anything.
