HealthVault Connect Center - Onetouch Ultra 2 BG Meter - COM Port Invalid Message RRS feed

  • Question

  • Hi,

    First of all thanks for supporting this effort to allow us to directly upload our meter readings.  I found the posting with instructions to install the Sinovo meter connection setup and followed it to the "T". 

    The page showed the device on the list as:

        "Prolific USB to Serial Port (COM3)" before I pressed the "Next >" button.

    I get the instruction page to "Turn Off My Device" and  check that it's off.

    I press the "Import Data" button,  I get the error:

        "Serial com port #3 is invalid"

    The error screen I get is:

    I have rebooted my computer, restarted the HealtVault Connection Center, unplugged and plugged the meter cable back in etc.

    What am I doing wrong?  I am on Windows 8.1 with the latest Microsoft HealthVault Connect center software.  (Yes, I manually selected the Sinovo device for my Ultra 2 OneTouch meter.  And it installed accordingly.  Great process!)

    I attempted to contact LifeScan and they indicate that they have never heard of this feature and can not support it.  So I am thinking that I need to get in touch with a techie at Sinovo for help.

    Thanks for any help you can provide.

    Please forgive me for this posting.  Apparently I didn't follow ALL the instructions.  I just happened to click on the "USB" icon on the page and it allow me to pull up an driver installation instructions provided by Sinovo.  Even, though this was a bit techie for most folks, I was able to accomplish it.  I'm posting the directions here from Sinovo that were most helpful.


    Unfortunately some older Prolific chipsets are not supported by Windows 8.x anymore. The discontinued chip versions
    are PL-2303H, PL-2303HX (RevA) or HXA and PL-2303X or XA. Please refer to Prolific for more detailed information:

    With the following steps you are able to still use cables with that chipset with Windows 8.x:

    * Connect the cable to your Win8.x machine and wait for Windows installation of the standard drivers.

    * Open the device manager and make sure that your cable is shown in the COM-Port section
      though as not working port with the yellow icon.

    * Use the sys-files of this package to make the driver work by copying the appropriate file (32Bit OR 64Bit!)
      to the folder: \Windows\System32\Drivers\  You'll need to overwrite the existing file.

    * Re-plug the cable and check that the yellow warning icon is gone.

    * In case that you encounter problems that Windows Update is always trying to update the driver with the not
      working Win8-sys-file you can configure the permissions of the sys-file above and remove write access to the
      System process user.
