-Reinstalling a Reluctant USB Device

The Windows USB "plug and play" feature is not always successful.  

The steps below detail the removal of a partially installed device followed by the additional steps required to perform a fresh installation.  Before you begin, ensure that you have your hardware or software installation disk at hand.

  • Close all applications. Leave the USB hardware attached and turned on.

  • Right-click on the "My Computer" icon on your desktop then from the dialog box, left-click on "Properties".

  • Left-click on the "Hardware" tab and then on "Device Manager".

  • Scroll to the bottom of the list and expand the "Universal Serial Bus Controllers" entry.

  • Look for an X-Rite entry like "DTP94".  Chances are it is present but with a yellow warning icon indicating a problem with the installation.

  • Right-click on that entry and select "Uninstall".

  • After the uninstall is completed, disconnect the hardware from the PC.

  • Wait about 15 seconds then re-attach the instrument.

  • The "Found New Hardware" wizard should launch.

  • Follow its prompts.  If it asks for the product CD then insert your installation disk and continue.

 

In the majority of cases, the above steps will resolve the USB installation. If it does not, or the driver installation finishes but the device is still unusable, do the following:

  • Uninstall the device as in steps 2-7 above.
  • Search your system for "XRUSB.sys", "XRUSB.inf", "XRUSB.pnf", plus those relevant to the instrument  you are using, for example "DTP94.inf" and "DTP94.pnf."

  • Note the location of each of these files and delete them

  • Reboot the computer.

  • Download and install the latest version of ToolCrib 5.

  • Reconnect the instrument to a USB port on the computer.

  • When the "Found New Hardware" wizard starts, manually direct it to the USB driver folder within the ToolCrib 5 program installation. It is normally located at: C:\Program Files\X-Rite\Tools\ToolCrib\USB Driver

  • The Wizard should be able to finish the installation successfully. Remember to click "Continue Anyway" if you receive a prompt about "Windows Logo testing."

This procedure resolves problems with corrupted driver files or instances where multiple versions of the driver were installed on top of each other.
