&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;&lt;br /&gt;
== problems description ==&lt;br /&gt;
Scanning is failing because the scanner software can't find the device.&lt;br /&gt;
&lt;br /&gt;
lsusb shows scanner (so its not a driver problem)&lt;br /&gt;
 $  lsusb                                                                                                                                             &lt;br /&gt;
 Bus 001 Device 007: ID 04a9:190a Canon, Inc. CanoScan LiDE 210&lt;br /&gt;
&lt;br /&gt;
sane-find-scanner list the scanner&lt;br /&gt;
 # sane-find-scanner&lt;br /&gt;
 ...&lt;br /&gt;
 found USB scanner (vendor=0x04a9 [Canon], product=0x190a [CanoScan], chip=GL124) at libusb:001:006&lt;br /&gt;
&lt;br /&gt;
running xsane as root still reports &amp;quot;no devices available&amp;quot;... so it is not a user permission problem&lt;br /&gt;
&lt;br /&gt;
== Errors ==&lt;br /&gt;
xsane:  no devices available&lt;br /&gt;
simple-scan : similar to above&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
== root cause ==&lt;br /&gt;
Xsane backend not installed&lt;br /&gt;
&lt;br /&gt;
== solution ==&lt;br /&gt;
 1. lookup the required xsane backend for your scanner hardware here:  http://www.sane-project.org/cgi-bin/driver.pl&lt;br /&gt;
 2. add sane backend from above to make.conf (optional)&lt;br /&gt;
     SANE_BACKENDS=&amp;quot;the_name_of_your_backend_goes_here&amp;quot;&lt;br /&gt;
 3. add &amp;quot;usb&amp;quot; &amp;amp; &amp;quot;scanner&amp;quot; use flag to make.conf if needed&lt;br /&gt;
 4. recompile sane-backends&lt;br /&gt;
     # emerge -uavND --quiet sane-backends &lt;br /&gt;
&lt;br /&gt;
TEST&lt;br /&gt;
 # scanimage -L                                                                                                                                    &lt;br /&gt;
device `genesys:libusb:001:007' is a Canon LiDE 210 flatbed scanner&lt;br /&gt;
&lt;br /&gt;
success!  scanning now works&lt;br /&gt;
