<p>Greetings all,</p>
<p>I just bought this AIO Canon. It has both USB and Network, and I have it on the network. So far it's been doing what I need, but I have to use a Windows VM to talk to the scanner. I've captured network packets when using the windows VM, and it appears to be using ports 8510/8512. If I use the SANE Pixma configuration file to talk to it, I can see it sending packets over the network to the printer, but it fails to ID the printer.</p>
<p>The Windows INF file seems to indicate driver support for the following:</p>
<p>"Canon MF745/746"=MF746C_USB,USB\VID_04A9&PID_27FA&MI_00<br />"Canon MF742/744"=MF742C_USB,USB\VID_04A9&PID_27FB&MI_00<br />"Canon MF741/743"=MF741C_USB,USB\VID_04A9&PID_27FC&MI_00<br />"Canon MF645"=MF645C_USB,USB\VID_04A9&PID_27FD&MI_00<br />"Canon MF642/643/644"=MF642C_USB,USB\VID_04A9&PID_27FE&MI_00<br />"Canon MF641"=MF641C_USB,USB\VID_04A9&PID_27FF&MI_00<br />"Canon MF745"=MF745C_USB,USB\VID_04A9&PID_2800&MI_00<br />"Canon MF642/644"=MF644C_USB,USB\VID_04A9&PID_2801&MI_00<br />"Canon MF Scan"=MFSCN_NW,CANON_MFNP&MFSCN<br />"Canon MF745/746"=MF746C_NW,CANON_MFNP&MF746C<br />"Canon MF742/744"=MF742C_NW,CANON_MFNP&MF742C<br />"Canon MF741/743"=MF741C_NW,CANON_MFNP&MF741C<br />"Canon MF645"=MF645C_NW,CANON_MFNP&MF645C<br />"Canon MF642/643/644"=MF642C_NW,CANON_MFNP&MF642C<br />"Canon MF641"=MF641C_NW,CANON_MFNP&MF641C<br />"Canon MF745"=MF745C_NW,CANON_MFNP&MF745C<br />"Canon MF642/644"=MF644C_NW,CANON_MFNP&MF644C</p>
<p><br /></p>
<p>When I plug the printer in via USB and run sane-find-scanner, it gives me the following:</p>

<p><trying to find out which USB chip is used><br />could not claim USB device interface<br />found USB scanner (vendor=0x04a9 [Canon], product=0x27fc [MF741C/743C]) at libusb:003:008</p>
<p><br /></p>
<p>I dunno if any of this is helpful, but if anyone cares to take a stab at this, I'm willing to test.</p>
<p><br /></p>
<p>Thanks in advance.</p>
