Firmware update of MC7455 timing out.

I'm trying to use the firmware update tool to change the current firmware
(SWI9X30C_02.08.02.00 r5428 CARMD-EV-FRMWR2 2016/01/06 20:38:53) to the
verizon firmware available on the Sierra Wireless site:

I have tried the following command but I am getting an error, any ideas? I
have tried with several MC7455's and I have been able to upgrade MC7304
firmware previously without a problem.

qmi-firmware-update --update -w /dev/cdc-wdm0

loading device information before the update...

setting firmware preference:

  firmware version: ''

  config version:   '002.034_000'

  carrier:          'VERIZON'

rebooting in download mode...

download mode detected

error: error creating device: timed out waiting for the response
