U142 Driver Release Notes ========================= ================================== PLEASE READ THESE NOTES CAREFULLY! ================================== Installation Instructions ========================= New Installation ---------------- 1) Extract all the files from the elu142.zip file to a folder on your hard disk. 2) Connect the U142 adapter to the USB port on your computer. 3) Select "Install from a specific location (Advanced)", navigate to the folder containing the files and follow the on screen instructions. Updating an existing installation --------------------------------- 1) Extract all the files from the elu142.zip file to a folder on your hard disk. 2) Connect the U142 adapter to the USB port on your computer. 3) Go to the "Device Manager" and right-click on the "U142 USB to CardBus Adapter" and select "Update Driver..." 4) Now DISCONNECT the U142 from the USB bus. 5) Select "Install from a specific location (Advanced)", navigate to the folder containing the files and follow the on screen instructions 6) (Skip this step if everything is OK!) If at this point the Device Manager goes unresponsive (give it plenty of time!) then reboot the PC and copy the elu142.sys file to the c:\windows\system32\drivers folder. 7) Connect the U142 and check the Device Manager for successful startup of the "U142 USB to CardBus Adapter". Uninstalling the Driver ----------------------- 1) Go to "Control Panel->Add or Remove Programs" 2) Select "U142 Diagostics Port Driver" and click "Change/Remove" 2) Select "U142 Adapter Driver" and click "Change/Remove" Activity LED Behaviour ====================== The bicolour (red/green) LED on the U142 adapter is used by the driver to indicate activity and successful installation of the Datacard. 1) "Off" -- ----- USB bus powered (or disconnected from USB bus!), no card in slot. 2) "On", RED -- ----------- Card detection and enumeration is in progress. 3) "On", GREEN -- ----------- Card is inserted recognised & enumerated, or in the process of enumeration with OS, everything is OK! 4) Mostly "off" short flash of GREEN once every approx 1 second -- ------------------------------------------------------------ External power is connected, USB bus connected, no card in slot. 5) Alternating RED-GREEN flashing, period approx 1 second -- ------------------------------------------------------ This indicates an error condition. Either the card is incompatible with the U142 (ie it's not a 32-bit CardBus card or the card is not supported), or there was an error during card enumeration. Check the card is in the Compatible Card List (below) and try ejecting the card and re-inserting. Compatible Card List ==================== Please see our web site for the latest list of compatible cards... http://www.elandigitalsystems.com/support/ufaq/supportedcards.php Known Issues ============ 1) Dell Latitude C840 Model Number:PP01X. External power supply or "Y" cable is required for correct operation of the U142. 2) Some "Dashboard" software supplied by the card operators (ie "Vodafone Mobile Connect" and Verison software) do not recognise card. Please refer to Elan any problems you may find! When submitting your report, please refer to the following web page: http://www.elandigitalsystems.com/support/debugging.php In the registry, please set the HKLM\SYSTEM\CurrentControlSet\Services\elUsbU142CardBus\Parameters\DebugFlags DWORD value to 0x0003FFFF and submit the DebugView logs with your report. PLEASE(!) make sure the DebugFlags is set whilst the problem occurs, only then we will be able to debug the problem! BTW: Setting DebugFlags will restrict the performance of the U142. Restore to 0 once you have submitted your report.
