                                  Version 2.0.0 
                                October 20, 2009
                                Elo TouchSystems

================================================================================    


Summary of new features & changes in driver v2.0.0:
---------------------------------------------------

  1. Supports latest 32 bit(i686) Linux kernels(kernel 2.6.25 and newer). It has 
     been tested on SLES 11 and Ubuntu 9.04 Linux distributions.

  2. Elo APR touchscreen driver components now require the new libusb-1.0 
     library support (older libusb-0.1 library will not work). Most newer Linux 
     distributions have started shipping this library(update to the popular 
     libusb-0.1 library) as a part of their standard release. Customers can also 
     download and compile the libusb-1.0 library from source available at libusb 
     website. This driver will NOT work with the older libusb-0.1 library.

  3. Supports only one video and one APR touchscreen configuration. Plug and 
     play option requires UDEV support in the Linux distribution. The driver 
     requires Xorg Xwindows to provide touch input to the Xserver. 
 
  4. Provides support for different APR modes tailored to suit various 
     applications [Point of Sale / General / Signature / Gaming] through driver 
     commandline options. See the readme.txt for various commandline options 
     available for the Elo APR driver(eloapr).  

  5. Provides support to optimize the APR driver modes further using custom 
     parameters. If the standard APR modes are not suitable, please contact Elo 
     tech support for help with custom APR parameters.

  6. Provides touchscreen support for various video rotation modes [0, 90, 180 
     and 270 degree angles] using driver commandline option. 

  7. Provides beep on touch feature by default, but can be disabled using driver 
     commandline option.

  8. Provides option to bypass the X authentication procedure to support Xorg 
     Xservers that do not require authentication (Embedded systems) using driver 
     commandline.
 
  9. Provides graphical window to display progress of touchscreen 
     characterization data download. 

  10. Provides graphical and commandline based control panel utilities. 



================================================================================    


Known Issues in driver v2.0.0 :
-------------------------------

  1. In certain Linux distributions, when the Properties tab in the graphic 
     control panel or the diagnostics option (option 7) in the commandline 
     control panel is selected, a touch input may be needed to display the 
     device information.
