Elo Touch Solutions

**********************************************************************

1. Special note and Known Issues:

   1.1 Due to Windows XP's issue with SHA2, v5.9.0 does not support
       pre-install (drivers installed without touch device been
       connected), nor silent install (drivers installed without
       user's presence or interaction). All touch monitors must be
       connected to the system at time of installation.

       During standard installation, users need to manually click
       away all Microsoft's driver digital security warnings to
       complete the installation.

       Each time a new device is connected, the driver has to be
       re-installed again.

       User has the option to disable XP system's driver signing
       enforcement with steps below:

         Control Panel-System-Hardware-Driver Signing-Ignore

       Once XP's driver signing requirement is turned off, the user
       can do silent installation of v5.9.0. The user can restore 
       the system's driver signing settings anytime.
 
   1.2 For 2521 (PID 0x27) controllers with firmware versions older
       than 6.2, sometimes the touchscreen does not respond to
       touches in either the upper or lower 1-inch region of the
       monitor. In this case, the monitor needs to be power-cycled,
       then re-calibrated to restore normal touch. If power-cycling
       the monitor does not work, the utility EloCalMgr.exe 
       (located in the target installation folder) can be used to
       reset the controller.  

   1.3 IR Beam Monitoring: After the user dismisses the alert box,
       it will show up again if touch monitor’s USB cable is
       re-plugged or the Property page of EloConfig is opened again.
       This feature is not suitable to be used with EloTouchZones,
       the user may not be able to dismiss the alert prompt box if
       the box happens to be inside an area where touch has been
       disabled.

   1.4 User applications written with Elo's single-touch 5.8 APIs
       will not work with v5.9.x; and these applications need to be
       updated (re-compile and link) based on the new header
       EloInterface.h in order to work with v5.9.x.

   1.5 When switching between admin and non-admin user accounts, users
       need to logout the current session and login with the new
       account credentials. Only one user can logged in at any time.

   1.6 The driver does not support XP systems with 2 serial touch
       monitors if one of the serial (RS232) touch monitors is 
       identified as PID 0x820.

   1.7 This release does not support 25-point calibration. For users
       who need this feature, please user Elo Single-touch v5.8.2.

2. History of Changes:

   v5.9.0: Initial release of new XP-only touch driver. This is the
           successor to Elo Single-touch driver v5.8.2.
