Is there a USB driver-only installer for the LabPro?

There is a LabPro USB driver-only installer for Windows.

Browse to
http://www.vernier.com/drivers/

and download the LabPro Windows USB driver.

This installer will install the latest version of the LabPro USB driver. Note that the current version of the Logger Pro installer uses the same driver. If you are using Logger Pro, it is generally safer to run the latest version of the Logger Pro installer rather then put just the driver in place.

Most users will not need this update. Update your computer if
1) you are seeing any kind of blue screen failure relating to LabPro.
2) you have installed Logger Pro to a network location, which does not install the USB drivers to a local machine, and so LabPro does not work by USB. Run this installer on each local client machine.
3) you are using LabPro with LabView, and have not installed Logger Pro.
4) you have custom software and need to talk to LabPro via USB.
