New Canon LiDE60; and it seems to need a reference(?) in source

[Joe Altman]

I have this device:

# usbdevs -v
port 3 addr 2: high speed, power 500 mA, config 1, CanoScan(0x221c),
Canon(0x04a9), rev 3.06

#sane-find-scanner
found USB scanner (vendor=0x04a9 [Canon], product=0x221c [CanoScan],
chip=GL841) at libusb:/dev/usb4:/dev/ugen0

#scanimage -L
device `genesys:libusb:/dev/usb4:/dev/ugen0' is a Canon LiDE 60
flatbed scanner

#dmesg
ugen0: Canon CanoScan, rev 2.00/3.06, addr 2

I've read back to some archived questions, and it seems (I'm guessing)
that this scanner lacks a reference in these two files:

/usr/src/sys/dev/usb/uscanner.c
/usr/src/sys/dev/usb/usbdevs

I say this, because while the above queries turn up the correct
info[1] for the scanner, there is no uscanner0 device created in /dev/
on this system:

5.4-STABLE FreeBSD 5.4-STABLE #0: Sun Jan 22 21:00:53 EST 2006
root at a nondescript blue box:/usr/obj/usr/src/sys/ANNA2  i386

So my query: if my guess is correct, and who do I ask to patch the
relevant source?

I did look at the code, but wasn't certain how to translate from the
three outputs above into an appropriate syntax.

[1] The sane project seems to agree, in that it lists the scanner as
supported in the genesys backend, as of the most recent version of the
sane-backends, 1.0.17.
