Current status unsupported
[300168.897925] usb 8-1: Product: CANON DR-2020U
[300168.897931] usb 8-1: Manufacturer: CANON
usbid: 1083:1625 Canon Electronics, Inc.
Canon provided linux driver, 386 only, probably not supported.
The driver consists of sources depending on sane, some configs and two
stripped 32-bit ELF binaries:
The name suggests in should be supported by canon_dr, but the DR2020U
binary references internally another USB VID and PID
Vid_1083&Pid_162e which is for Canon ImageFormula 101, supported
in /etc/sane.d/genesys.conf ,
I'm ready to test it but it's visible by sane-find-scaner and not by
The same binary also refers IC UPD8894CY which according to aliexpres is
CCD Linear Image Sensor.
1. Could somebody tell why Canon DR-2020U is unsupported ? From some reason
you are unable to support it, or it's due to lack of resources ? on website
there is info: "GL84x?" What does it mean ?
2. Is that chip the one you require to termine how to handle this device in
backend or do I need to disassembly?
3. Trying to compile driver with propertiary binaries I stuck at:
*** No rule to make target
`../../sane-backends-1.0.19/sanei/sanei_net.lo', needed by `
Is this problem with SANE?
4. How can I help you with development? - I have programming, electronic,
disassembly and RE general skills, have physically that device. Don't have
deep knowledge about sane backends architecture and how Canon proprietary
implementation is consistent with that.
