Thanks to help from Warren Block and Lowell Gilbert, I now have the offical ported version of sane-backends-1.0.21 running. Unfortunately, it's behaving the same way as before, apparently not properly recognizing the USB device. It
Does anyone have experience using this? Or better yet, some sense of what it needs from the USB side? A clue on enabling the internal debugging would also be welcome.

=============================================
I have added
product CANON CS8800F 0x1901 CanoScan 8800F
to /usr/src/sys/dev/usb/usbdevs. I have also added
{{ USB_VENDOR_CANON, USB_PRODUCT_CANON_CS8800F }, 0 },
to /usr/src/sys/dev/usb/uscanner.c
When I run scanimage -L I get
---------
device `pixma:04A91901' is a CANON Canoscan 8800F multi-function peripheral
-------
When I run scanimage -d pixma:04A9101 I get
--------
scanimage: sane_read: Invalid argument
--------
Which I have traced to a defaulted fill routine in a table.
scanimage --help gives me a message ending with
-------
Options specific to device `pixma:04A91901':
Scan mode:
--resolution auto||75|150|300|600|1200|2400|4800dpi [75]
Sets the resolution of the scanned image.
--mode auto|Color|Gray [Color]
Selects the scan mode (e.g., lineart, monochrome, or color).
--source Flatbed|Transparency Unit [Flatbed]
Selects the scan source (such as a document-feeder).
--button-controlled[=(yes|no)] [no]

Gamma:
--custom-gamma[=(auto|yes|no)] [yes]
Determines whether a builtin or a custom gamma-table should be used.
--gamma-table auto|0..255,...
Gamma-correction table. In color mode this option equally affects the
red, green, and blue channels simultaneously (i.e., it is an intensity
gamma table).
Geometry:
-l auto|0..216.069mm [0]
Top-left x position of scan area.
-t auto|0..297.011mm [0]
Top-left y position of scan area.
-x auto|0..216.069mm [216.069]
Width of scan-area.
-y auto|0..297.011mm [297.011]
Height of scan-area.
Buttons:
--button-update
Update button state
--button-1 <int> [0]
Button 1
--button-2 <int> [0]
Button 2
Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.
List of available devices:
----------------------------
There is a /dev/usb/uscanner .
I haven't figured out how to turn on the internal debugging system, so my first question to someone who may have ported an earlier version is how to do that.
My second question is whether I have the USB entries right, and whether I need to do anything else to make this work.
And finally, I ask for any general wisdom or hints in dealing with SANE and SANE with USB devices.
