Getting an Epson Pefection 4490 Photo scanner going with Ubuntu GNOME Remix 12.10

My Epson¬†Perfection 4490 Photo scanner has been in my possession for a while now and its impossible to justify any replacement given that it both works well and digital photography has taken over from its film predecessor for me. Every time I go installing an operating system afresh, I need to reinstate it again and last year’s installation of Ubuntu GNOME Remix 12.04 only saw me do the deed recently. When I did so, it was brought back to me that I’d never gone and documented on here how this was done. Given that I sometimes use this place as a repository of stuff to which I need to refer again in the future, it seemed remiss of me so here it is for you all.

Though I had XSane and SimpleScan already installed on the system, Sane wasn’t on there so I went and added it and a few other extras using the following command:

sudo apt-get install sane sane-utils libsane-extras

Then, it was onto the Epson website for their Perfection 4490 Photo Linux drivers since Sane’s support for this scanner seemingly remains incomplete even though it pre-dates my move to Linux in 2007. Three files were needed and the following commands install them (depending on when you do this, the file names may be different so just change them to whatever they are for you; it can be done with a single command too but there is not enough girth for that here):

sudo dpkg -i iscan-data_1.22.0-1_all.deb
sudo dpkg -i iscan_2.29.1-5~usb0.1.ltdl7_i386.deb
sudo dpkg -i iscan-plugin-gt-x750_2.1.2-1_i386.deb

With those in place, there was one other task that needed doing so that scanning could be done without resorting to running scanning software using sudo privileges. To free up the access to a normal user account, I needed a HAL device information file. These normally are in /usr/share/hal/fdi/ but they change every time an installation so any modifications that you may make are going to be lost. Therefore, there is no point modifying either /usr/share/hal/fdi/preprobe/10osvendor/20-libsane.fdi or /usr/share/hal/fdi/preprobe/10osvendor/20-libsane-extras.fdi where scanner information usually is to be found.

The first task in creating an fdi file was to issue the lsusb command and look for a line corresponding to my scanner. This is the one that I got:

Bus 001 Device 004: ID 04b8:0119 Seiko Epson Corp. Perfection 4490 Photo

From this, I gleaned the manufacturer ID and model ID as 04b8 and 0119, respectively. These are needed later on. Next I needed to create the hal/fdi/preprobe/ folder structure under /etc since it was there. Then, I created epson4490photo.fdi in the bottom folder of the tree (/etc/hal/fdi/preprobe/epson4490photo.fdi) as follows:

cd /etc/hal/fdi/preprobe/ && sudo touch epson4490photo.fdi

Then, I edited the new file using the following command:

gksu gedit epson4490photo.fdi &

When open, I added in the following text:

<?xml version=”1.0″ encoding=”UTF-8″?>
<deviceinfo version=”0.2″>
<device>
<match key=”info.subsystem” string=”usb”>
<!-- Epson Perfection 4490 Photo -->
<match key=”usb.vendor_id” int=”0x04b8″>
<match key=”usb.product_id” int=”0x0119″>
<append key=”info.capabilities” type=”strlist”>scanner</append>
<merge key=”scanner.access_method” type=”string”>proprietary</merge>
</match>
</match>
</match>
</device>
</deviceinfo>

It’s all in XML so the place to look is immediately beneath the scanner name comment. The int attributes of the two match elements immediately following the comment line are populated using the information from the lsusb command output with 0x prefixing both the manufacturer and model identifiers. The element with a key attribute of usb.vendor_id is the former and that with a key attribute of usb.product_id is the latter. With epson4490photo.fdi saved, I rebooted the machine to restart HAL and all was as I wanted it to be apart maybe from XSane making complaints that seemed not to be of any actual consequence. With Epson’s Image Scan! and Simple Scan on the PC, there’s no need to be bothered with those messages. Choice is good when you have it, especially when you have expended some effort to get that far.

Want attention? Just mention Ubuntu…

According to Google Analytics, visitor numbers for this blog hit their highest level one day last week. I suspect that I might have been down to a mention of two of my posts on tuxmachines.org. Thanks guys. Feedburner activity has been strong too.

That brings me to another thought: the web seems a good place for Ubuntu users to find find solutions to problems that they might encounter. I certainly found recipes that resolved issues that I was having: scanner set up and using another hard drive to host my home directory, all very useful stuff. When I last played with Linux to the same extent that I am now doing, the web was still a resource but it wouldn’t have been as helpful as I found it recently. I suppose that there are people like me posting tips and tricks for computing on blogs and that makes them easier to find. That’s no bad thing and I hope that it continues. Saying that, I might still get my mits on an Ubuntu book yet…
