Hi,
Best thing is to create an issue here:

Hello,
I got CanoScan LiDE 400 (ID 04a9:1912 Canon, Inc. LiDE 400) and trying
to make all front buttons work with scanbd. Scanner is recognized as
pixma device.
$ scanimage -L
device `pixma:04A91912_46710F' is a CANON CanoScan LiDE 400
multi-function peripheral
There are 5 front buttons
(https://ij.manual.canon/ij/webmanual/ScanUtility/All/LiDE%20400/1.0/EN/SU/screens/su129_c.gif
<https://ij.manual.canon/ij/webmanual/ScanUtility/All/LiDE%20400/1.0/EN/SU/screens/su129_c.gif>),
left to right:
- [Scan start button]
- [Finish button]
- [Auto scan]
- [Copy]
- [Send]
Scanbd/sane is interpreting those as:
- [Scan start button] - recognized as Button-1 (PIXMA_EV_BUTTON1 -
color scan)
- [Finish button] - recognized as Button-2 (PIXMA_EV_BUTTON2 - b/w scan)
- [Auto scan] - recognized as Button-1 (PIXMA_EV_BUTTON1 - color scan)
- [Copy] - recognized as Button-1 (PIXMA_EV_BUTTON1 - color scan)
- [Send] - recognized as Button-1 (PIXMA_EV_BUTTON1 - color scan)
So there is a lot of duplication and instead of 5 buttons one can
effectively use only 2. This is what I see when capturing USB packets
with usbmon loaded.
cat /sys/kernel/debug/usb/usbmon/3u:
- [Scan start button] - 0:1024 32 = 00000000 01000000 00000000
00000000 00000005 00000000 00000000 00000000
- [Finish button] - 0:1024 32 = 00000000 01000000 00000000 00000000
00000006 00000000 00000000 00000000
- [Auto scan] - 0:1024 32 = 00000000 01000000 00000000 00000000
00000002 00000000 00000000 00000000
- [Copy] - 0:1024 32 = 00000000 01000000 00000000 00000000 00000001
00000000 00000000 00000000
- [Send] - 00000000 01000000 00000000 00000000 00000003 00000000
00000000 00000000
Would it be possible to add definitions for all buttons based on the
information above?
A few information about my system:
Arch Linux x86_64 (kernel 5.13.6-arch1-1), sane 1.0.32-3, scanbd 1.5.1-5
Thank you, jose
