How to install Epson Stylus CX5600 on Ubuntu 10.04

I’ve found many tutorials about this topic, but only one, found in Luis Gallardo’s blog, worked for me.

Luis’s tutorial explain how to install on Ubuntu 9.10, so some steps are not necessary. I’ll show necessary steps to install on Ubuntu 10.04.

You need to download drivers from Avasys site. Go to this link, scroll down the page, choose “Epson Stylus CX4300/CX4400/CX4450/CX5500/CX5600/DX4400/DX4450“, “Ubuntu” and version “10.04“, click “Next”.

Now, download “iscan-data_1.9.0-1_all.deb“, “iscan_2.26.4-2.ltdl7_i386.deb” and “iscan-plugin-cx4400_2.1.3-1_i386.deb“. After, run commands:

sudo dpkg -i iscan-data_1.9.0-1_all.deb
sudo dpkg -i iscan_2.26.4-2.ltdl7_i386.deb
sudo dpkg -i iscan-plugin-cx4400_2.1.3-1_i386.deb

Make sure the scanner is connected and turned on and run command


Should appear a list of devices connected to the USB ports, like this:

Bus 003 Device 004: ID 04b8:083f Seiko Epson Corp. Stylus DX4450
Bus 003 Device 003: ID 04fc:05d8 Sunplus Technology Co., Ltd 
Bus 003 Device 002: ID 04f3:0216 Elan Microelectronics Corp. 
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 001 Device 003: ID 18e3:9101 Fitipower Integrated Technology Inc 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

The first line (“Bus 003 Device 004: ID 04b8:083f Seiko Epson Corp. Stylus DX4450“) means the scanner was detected on address 003:004.

These steps are enough for the scanner be detected for XSane, but only root can to use.

To fix this “little” problem, edit file /lib/udev/rules.d/40-libsane.rules and add the following lines:

# Epson CX5600
ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="083f", MODE="0664", GROUP="saned", ENV{libsane_matched}="yes"

Turn off and turn on your scanner. To see if the problem was fixed, run command lsusb again. The output should be like this:

Bus 003 Device 004: ID 04b8:083f Seiko Epson Corp. Stylus DX4450

Note the number of “Bus” and “Device”, with them run command

ls -l /dev/bus/usb/<BUS>/<DEVICE>

Replace <BUS> and <DEVICE> by respective numbers:

ls -l /dev/bus/usb/003/004

You will see something like

crw-rw-r--+ 1 root saned 189, 129 2011-07-01 14:01 /dev/bus/usb/003/004

Now you can to use your scanner with any user owned to group saned.

Installing multi-language support in Windows 7 Professional and Home Premium editions

Multi-language support is native in Windows 7 Enterprise and Ultimate editions, but, following this tutorial you be able to alternate entire many languages in Professional and Home Premium editions.

First you’ll need of Vistalizator. This application enable to install muti-language support in all Windows 7 editions and, how it’s portable, you don’t need install it. Download it clicking here.

After, download the languages for architecture x64 (64 bits without Service Pack or Service Pack 1) or x86 (32 bits without Service Pack or Service Pack 1).

Now run the Vistalizator and click in “Add languages”.

Browse for language file that you desire and click in “Open”.

Will be show the message below, then click in OK to proceed

A new window will be open with language data and your description, then click in “Install Language”.

Wait the installation process be done.

Now, the Vistalizator will show for you the languages installed in your machine and there will be the recently installed language.

Reboot Windows and voilá. 😉

Now you have Windows 7 Professional/Home Premium with multi-language support.

The only bad thing that I noticed was: all time that you want to change the language, you must to use the Vistalizator, because the Windows 7 Professional and Home Premium doesn’t support this feature natively.

Solving problems with removal of the external HD in Windows 7

Some times I had problems when disconnected my external HD using Windows’ s Removal Device Assistant, the most frequently was “This device is currently in use. Close any programs or windows that…”. This message appeared even with all programs closed.

After checked Windows settings, process and services, I noticed that the problem was in service “Windows Media Player Network Sharing Service”, forcing me to stop it before remove the device.

But still, this solution not is right, then I found the most right:

The service “Windows Media Player Network Sharing Service” is responsible to share your media files (musics and videos) in your network or in the internet (like your name sounded. 🙂 ). This is default setting in Windows 7, to disable it…

Click in Start menu, type “Network and sharing center” and select the application. Like show in the image

Click “Choose homegroup and sharing options”

Clique na opção “Escolher opções de grupo doméstico e de compartilhamento”

Now click on “Choose media streaming options…”

Change option of item “Media programs on this PC and remote conections…” to “Blocked”.

Finish! From now you can remove your external hard drive or other removable storage devices without problems.


Enabling Windows Media Player bar in Windows 7 taskbar

Unfortunately Windows Media Player 12,  already installed with Windows 7, has no support to minimize as toolbar in the taskbar. To enable this bar, just need copy a file from Windows Media Player for Windows Vista. Now I will show how do this:

1. You will need of a dll called wmpband.dll, that come with Windows Vista. If you not own it, download here (2590) (this ZIP contains 32 and 64 bits versions);

2. Copy the file (32 or 64 bits, depends your Windows) to Windows Media Players installation directory, in my case “C:\Program Files\Windows Media Player“;

3. Now check if “Windows Media Player Network Sharing Service service is stopped. To do this, click in Start and, in the search box, type “Services” and click in the respective list item. Look for service and stop it, if running.

4. Open the Command Prompt with administrator privileges. Star > All Programs > Accessories > right click in “Command Prompt” and click “Run as Administrator”.

5. Type command regsvr32C:\Program Files\Windows Media Player\wmpband.dll“, replace the path of the directory where the dll is.

6. Open Windows Media Player and minimize it. Then right click in the taskbar > Toolbars > select Windows Media Player.

6. Abra o Windows Media Player e então o minimize-o. Depois clique com o botão direito na barra de tarefas > Barra de Ferramentas > Windows Media Player.

7. And voilá.

Microsoft should have kept this feature natively, I know people who use this resource, I inclusive.
