USB Measurement Device Setup

LibUSB-Win32 and Friends

To use USB devices LibUSB-Win32 must be installed.   Please go here for installation files.  This site has two installation files that can be reached from the Downloads page.  These include the LibUSB-Win32 Device Driver and the LibUSB-Win32 Filter Driver.  At a minimum you will need the LibUSB-Win32 Device Driver installed on your machine.  You can optionally use the LibUSB-Win32 Filter Driver instead of using the ArgyllCMS specific device drivers that are also included with LProf.  But it has not been extensively tested and some devices may not work correctly when you use the LibUSB-Win32 Filter Driver.

Installing the ArgyllCMS Device Driver

For a new device this is fairly simple.  First plug in the device and you will be greeted by the Windows "New Hardware Found" dialog.  This dialog will ask you to install drivers for the device.   Use this dialog to navigate to the location of the ArgyllCMS drivers.  These will be located in <lprof install location>\share\lprof\drivers.  Select the *.inf file that is correct for your device and finish running the dialog,  

If you have already installed the vendors drivers then you may need to switch to the ArgyllCMS drivers if the
the LibUSB-Win32 Filter Driver does not work for your device (see next section).  To switch drivers use the Windows Device Manager "Update Drivers" dialog.  This will allow you to select the ArgyllCMS drivers for your device.  You can also use the "Update Drivers" "Display a List of Known Drivers" dialog to switch back and forth between the vendors driver and the ArgyllCMS driver if you should need to do this.  

The LibUSB-Win32 Filter Driver

It may be possible to use this driver along with the drivers supplied by the device vendor rather than the ArgyllCMS drivers for your device.  Testing with a EyeOne Display LT did uncover some issues with this particular device  and using the LibUSB-Win32 Filter Driver.  If the LibUSB-Win32 Filter Driver works for your device then you can use your device with other software without having to switch drivers.

Huey HID

The Huey is a HID device and does not need to have a driver installed when the device is first connected.  

ColorVision Spyder 2

If you have a ColorVisions Spyder 2 you will have additional steps that are needed to fully install it.  Please see the Spyder 2 installation help page for information that applies to all platforms for this device.
