/*
* This program supports loading firmware into a target USB device
* that is discovered and referenced by the hotplug usb agent. It can
* also do other useful things, like set the permissions of the device
* and create a symbolic link for the benefit of applications that are
* looking for the device.
*
* -I <path> -- Download this firmware (intel hex)
* -t <type> -- uController type: an21, fx, fx2, fx2lp, fx3
* -s <path> -- use this second stage loader
* -c <byte> -- Download to EEPROM, with this config byte
*
* -L <path> -- Create a symbolic link to the device.
* -m <mode> -- Set the permissions on the device after download.
* -D <path> -- Use this device, instead of $DEVICE
*
* -V -- Print version ID for program
*
* This program is intended to be started by hotplug scripts in
* response to a device appearing on the bus. It therefore also
* expects these environment variables which are passed by hotplug to
* its sub-scripts:
*
* DEVICE=<path>
* This is the path to the device is /proc/bus/usb. It is the
* complete path to the device, that I can pass to open and
* manipulate as a USB device.
