fedora 17: making viewsonic td2220 touchscreen monitor work

just got a viewsonic td2220 touchscreen without checking if it has linux support because i was thinking it's just a simple input device. but it didn't plug-and-play. haha

checking viewsonic's website, to date, they only support windows boxes for td2220.

also, to date, google has no answer for it yet, too.
(yep, google doesn't know everything. but it does help a lot in finding what you're looking for! hahaha)

so to make my new touchscreen monitor work, i hunted a driver provider for touch products. good thing there's elo touch solutions (http://www.elotouch.com).

follow the steps below to have your viewsonic td2220 work on your fedora:

1. download drivers (http://www.elotouch.com/Support/Downloads/dnld.asp)
under linux, i used their 32bit multi-touch usb driver, since i'm using the monitor for a 32bit box

2. download instructions file for your more detailed guide
i'm summarizing the steps here so you won't have to read the instructions guide

3. extract and copy the drivers into /etc/opt/elo-mt-usb and prepare files for install

# tar -zxvf SW602247_Elo_Linux_MT_USB_Driver_v2.0.0_i686.tgz
# cp -r ./bin-mt-usb/  /etc/opt/elo-mt-usb

# cd /etc/opt/elo-mt-usb
# chmod 777 *
# chmod 444 *.txt

# cp /etc/opt/elo-mt-usb/99-elotouch.rules /etc/udev/rules.d


4. compile a driver for your system from source (this will require you to install make, gcc and kernel-devel)

# cd /etc/opt/elo-mt-usb/elo_mt_input_mod_src
# make
# make install


5. test if it works (mine worked instantly! woot!! but that means i don't know how to solve your problem if yours doesn't work. haha)

# /etc/opt/elo-mt-usb/loadEloMultiTouchUSB.sh

6. make it run on boot

# cp /etc/opt/elo-mt-usb/elorc /etc/init.d

edit /etc/init.d/elorc to make it chkconfig compatible. i added the ff lines:

# chkconfig: 235 90 10

# decription: viewsonic touchscreen

add your start up script to checkconfig

# chkconfig --add elorc

7. reboot and rest. and because it's the seventh, rest! hahaha

panis! XD

p.s. make sure that your kernel and kernel-devel are of the same version. if you just updated your kernel to be of the same version as your kernel-devel, restart your box before retrying.
