I'm not a Mac expert myself, but I'll poke around things and see what I can do....

The "process" here under is probably not an application, but runs in background, it may be a printing daemon or service started after boot, which locks access to the usb port. 
I really know nothing about Mac OS X, to help you find it, maybe stop a printing service would help.

I'm running the command from terminal at system boot, so there really should not be anything else open....is there some way to check this, anyway, so that I might be sure of it?
Thank you for your patience....

Well, not exactly something new, the 2 logs are somehow equivalent, but one gives a little bit more details:[pixma] en1 is not a valid IPv4 interface, skipping...
[pixma] en1 is IPv4 capable, sending broadcast..

[pixma] scanner discovery finished...
[pixma] pixma_open(): Canon imageClass MF6500
[sanei_usb] sanei_usb_open: trying to open device `libusb:005:002-04a9-2686-00-00'
usb_os_open: 04a9:2686
usb_os_open(USBDeviceOpenSeize): another process has device opened for exclusive access

usb_set_configuration: called for config 1
USB error: usb_set_configuration(SetConfiguration): device not opened for exclusive access
[sanei_usb] sanei_usb_open: libusb complained: usb_set_configuration(SetConfiguration): device not opened for exclusive access

usb_os_close: 04a9:2686
[pixma] pixma_connect() failed EINVAL
[pixma] pixma_open() failed EINVAL
[pixma] pixma_close(): Canon imageClass MF6500
scanimage: open of device pixma:04A92686 failed: Invalid argument


And I think we're back to a few messages ago in this thread, so first, could you locate this other process (maybe printer ?) which locks the usb device, and stop it ?

Ditto: here are the new logs. 
Something new sprouted out, at their very end....hope it's useful.
