Hello,<br>I've got a Canon MP180 scanner that is not working with sane.<br>I've downloaded the source code of the driver pixma_mp150 that's part of the sane project. It supports the following scanners : MP150, MP170, MP450, MP500, MP530, MP800, MP800R and MP830.
<br><br>I want to make my scanner to work with this backend, but I don't know if it's safe.<br><br>I've searched for the word MP170 :<br>$ grep -ri MP170 *<br>pixma.desc::model "PIXMA MP170"<br>pixma_mp150.c:#define MP170_PID 0x170a
<br>pixma_mp150.c: DEVICE("Canon PIXMA MP170", MP170_PID, 1200, 0),<br>( and some html pages, manpages... )<br>_________________<br>Details of the files found:<br>*pixma.desc @ line 33:<br>:model "PIXMA MP170"

<br>- Its capability : 0 (nothing)<br>_________________<br><br>With the command sane-find-scanner I've this :<br>found USB scanner (vendor=0x04a9 [Canon], product=0x1715 [MP180]) at libusb:002:002<br><br>So I think that my scanner has these specific values :
<br>- Its name : "Canon PIXMA MP180"<br>- Its usbid : "0x04a9" "0x1715"<br>- Its resolution : 1200 (this resolution is the same)<br>- Its capability : 0 (nothing because I don't know)<br>
<br>If I want to use this driver, I only need to add the entries for this scanner :<br><br>--- pixma.desc.orig 2007-01-20 19:49:56.000000000 +0100<br>+++ pixma.desc 2007-01-20 19:50:23.000000000 +0100<br>@@ -35,6 +35,11 @@
