Hi Matthias, 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: ... Buttons: --button-update 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 [pixma] --button-1 <int> [1] [read-only] Button 1 --button-2 <int> [0] [read-only] Button 2 --original <int> [0] [read-only] Type of original to scan --target <int> [1] [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.
