Hi, Ceri,
<BR>
yes, my scanner is usb. It is essential that you have a kernel with proper
<BR>
usb support. I don't know much about the latest 2.4.x kernels, for me version
<BR>
2.2.18 is allright. I downloaded it as source from kernel.org and compiled it
<BR>
(under Calder Open Linux 2.4) to suit my needs, espescially usb.
<BR>
You can find most useful hints at <A HREF="http://www.linux-usb.org">http://www.linux-usb.org</A> (and in your
<BR>
kernel documentation at /usr/src/linux/Documentation/usb, esp. the file
<BR>
scanner.txt), but I can give you the relevant kernel config info:
<BR>
...
<BR>
#
<BR>
# USB support
<BR>
#
<BR>
CONFIG_USB=m
<BR>
CONFIG_USB_DEVICEFS=y
<BR>
...
<BR>
CONFIG_HOTPLUG=y
<BR>
...
<BR>
CONFIG_USB_UHCI=m ((yours might be: CONFIG_USB_OHCI=m, if in doubt, use both))
<BR>
...
<BR>
CONFIG_USB_SCANNER=m
<BR>
All other options in the usb section are not set, as I don't have any other
<BR>
usb devices.
<BR>
<P>After a successful kernel compile and installation of modules, you should
<BR>
make known the new device to you system:
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`mknod /dev/usbscanner0 c 180 48`
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`ln -s /dev/usbscanner0 /dev/usbscanner`
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;`chmod 666 /dev/usbscanner0`
<BR>
and load the modules:
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'modprobe usb-uhci'
<BR>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'modprobe scanner'
<BR>
Then sane should recognize your scanner, but other problems might occur which
<BR>
are device specific; see the faqs at the sane website.
<BR>
BTW: Which scanner are you using?
<BR>
Best wishes
<BR>
KP

<EM>&gt; How did you get Linux to see your scanner? I have just compiled
</EM><BR>
<EM>&gt; snapscan-20010411 and I cannot get the scanner recognised or even seen by
</EM><BR>
<EM>&gt; Linux. Is your scanner a USB one (it must be looking at the model number).
</EM><BR>
<EM>&gt; What is the secret to getting the USB connection to work?
</EM><BR>
<EM>&gt;
</EM><BR>
<EM>&gt; scanimage -L says ' No scanner detected...'
