uscanner firmware upload? (w/ sane?)

[Harald Schmalzbauer]

Hello,

I changend usbdevs and uscanner.c a bit so my Epson Perfection 3490 PHOTO 
attaches to uscanner0 instead of ugen0. (See patch below)

If I use this scanner on another supported operating system I can connect it 
to my FreeBSD machine and "scanimage" works fine.
But if I repower the scanner "scanimage" just hangs with -L.
The problem is that the scanner needs firmware to be uploaded when repowered.
I have the correct firmware binary and I also configured sane to use that but 
it seems sane doesn't upload the binary.
Is there any method to upload the firmware to uscanner with on board 
utilities?
Any other hints?

Thanks a lot,

-Harry
