i1Pro or i1Display2/LT Not Recognized by Windows PC

If you connect your i1 device to your Windows PC computer before installing the X-Rite application program you intend to use the device with, you will often encounter an error condition. Typically this will be seen when you open the X-Rite program (i1Match, i1Diagnostics), and you get a "device not found" message.Possible Reason:
