This was done eons ago in the form of a command-line utility; see the 
misc/ezload port.  I have also made a few changes as well.  If you have 
questions as to how it works / etc, let me know.

I personally prefer to do the firmware load & renumeration (the reboot 
onto the loaded firmware) in userspace.  Just add an entry like this in 
/etc/usb.conf:

device "Some Device"
         vendor  0xaaaa
         product 0xbbbb
         release 0xcccc
         attach "/usr/local/bin/ezdownload -v /dev/${DEVNAME}"

The device will attach as a ugen, then the firmware will be downloaded, 
the device reset, and then it will reattach as whatever it renumerates 
as.

Put the firmware file in /usr/local/share/usb/firmware.
