Please (1) activate debug messages with 'export SANE_DEBUG_PIXMA=11',
(2) push one of your scanners's buttons and
(3) read the button status with 'scanimage -A'.
You should receive something similar like this:
Update button state
[pixma] INTR T=1.580 len=32
[pixma] 00000000:00 10 00 00 00 00 00 00 00 00 00 00 00 00 00 00
[pixma] 00000010:00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
--button-1 <int>  [read-only]
--button-2 <int>  [read-only]
--original <int>  [read-only]
Type of original to scan
--target <int>  [read-only]
Target operation type
If you get lines with [pixma], please repeat this test ((2) & (3)) with
all buttons and provide the output from all buttons. Please write the
name of the button to the corresponding debug output.
If you don't get lines with [pixma], Sane doesn't receive the USB
interrupt from your scanner and I need to prepare a patch.
