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 ), 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
