What's left to be done is to be able to scan using an add-on device (canon flatbed scanner unit 101) that we have. It works like this - the main scanner is connected to the flatbed unit via USB cable, and the flatbed unit is connected to the PC via another USB cable (apparently the flatbed has a built-in usb hub). <br><br>I've connected the devices now as they should be connected, I continue to be able to scan via the main scanner. <br><br>The flatbed unit has an USB ID of its own, lsusb returns:<br>Bus 002 Device 023: ID 1083:162e Canon Electronics, Inc.<br><br>I can also see it in /var/log/messages:<br>Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: new high speed USB device number 26 using ehci_hcd<br>Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: New USB device found, idVendor=1083, idProduct=162e<br>Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: New USB device strings: Mfr=10, Product=11, SerialNumber=0<br>Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: Product: CANON Flatbed Scanner Unit 101<br>Nov 26 16:53:30 itp01 kernel: usb 2-1.3.1: Manufacturer: CANON<br><br>What can we do to make it work?

In that function, there is a section for<br>the DR-2510C. Copy that section, and change it to match the DR-3010C.<br>In your new section, also add this:<br><br>s->invert_tly = 1;<br><br>Then recompile and reinstall.
