If you send me your modification maybe I can do something with it. Best regards, Gernot

So right now, scanning over ethernet works, but over USB it doesn't work yet. Since the driver seems to be able to talk to the device, this is likely something small. What can I do to track down the USB problem and what tests can I run to make sure the device works as expected? Is there a standard set of tests to run? Hi, Great to hear that the device works at least over ethernet. I am afraid I do not know (yet) how to solve USB issues, perhaps you can activate the sane USB debug environment variables (see the various sane-* man pages, apropos should show you them) and send the output of that when you try sane as root (maybe better than sudo for this test).

For completely, please let me know also the specs of your OS distribution. I also noticed that the scanner is accesses as long as the usblp and the usb_storage kernel modules are loaded. As soon as I remove either one, scanimage -T gets a timeout when accessing the device. I don't know if that is significant. I think for modern distributions no-one should need to touch any kernel modules. USB devices should simply work. But some USB-related packages must be installed---these should be dependencies of sane-backends for your distro anyway though. Regards, Gernot

[sane-devel] support for Canon MG8150
I tried to use the device over ethernet and this seems to work better: Quoting Gernot Hassenpflug aikishugyo at gmail.com: On Mon, Nov 1, 2010 at 2:19 AM, ralph.gauges at bioquant.uni-heidelberg.de wrote: Hi, I recently bought a new multifunction device from Canon (MG8150) and as usually there are no linux drivers for the device from the manufacturer.

So after adding the lines you suggested, scanning over ethernet seems to work while scanning via USB does not work yet. Somehow when using the USB connection, the device is recognized as an MX870 while over ethernet it is correctly recognized as an MG8100 device. Ah, I have made a small mistake, I changed the wrong ID, maybe it is to late already. Now I fixed the ids again and the device is recognized as an MG8100 device over USB as well, but I still get the I/O error. So right now, scanning over ethernet works, but over USB it doesn't work yet. Since the driver seems to be able to talk to the device, this is likely something small. What can I do to track down the USB problem and what tests can I run to make sure the device works as expected? Is there a standard set of tests to run? Thanks Ralph running under linux. I have never written any device drivers, but I know C/C++ and I am fairly familiar with linux, so if you tell me what I can do to help, I will try. Hi, At the moment there is no specific support for the new devices, so you are most welcome to help. As there already exists code that might be able to support these devices without any (or not much) development please try the following, using the CVS sane-backends code. You can try adding the definitions near the end of pixma_mp150.c where similar definitions exist, like this: /* Latest devices (2010) Generation 4 CIS/CCD */ DEVICE (Canon PIXMA MP280, MP280, MP280_PID, 1200, 638, 877, PIXMA_CAP_CIS), DEVICE (Canon PIXMA MG5100, MG5100, MG5100_PID, 1200, 638, 877, PIXMA_CAP_CIS), DEVICE (Canon PIXMA MG6100, MG6100, MG6100_PID, 2400, 638, 877, PIXMA_CAP_CIS), DEVICE (Canon PIXMA MG6200, MG6200, MG6200_PID, 2400, 638, 877, PIXMA_CAP_CIS), DEVICE (Canon PIXMA MG8100, MG8100, MG8100_PID, 4800, 638, 877, PIXMA_CAP_CCD | PIXMA_CAP_TPU), and the USB ids near the start of the file under the existing ones, like this: #define MP280_PID 0x1746 #define MG5100_PID 0x1748 #define MG5200_PID 0x1749 #define MG6100_PID 0x174a #define MG8100_PID 0x174b Compile and then see if the device can work at all. Note the MG devices are sold under different names in different parts of the world, so the last 2 digits above are simply 00 to denote the family.
