Why does usb-creator-gtk require root access?
Solution 1:
Policy Kit foresees the following actions related to Usb Creator
$ pkaction --verbose | grep -A1 '\.usb' | less
com.ubuntu.usbcreator.bootloader:
description: Install the bootloader
--
com.ubuntu.usbcreator.format:
description: Format the device
--
com.ubuntu.usbcreator.image:
description: Image the device
--
com.ubuntu.usbcreator.mount:

These are actions that only root can execute, given that block devices are owned by root.
