Ik heb zelf alleen Weatherlink, geen VP2 en/of USB-kabel, dus kan niets in de praktijk uitproberen, alleen wat tips geven.
Bij een update schijnt belangrijk te zijn een oude USB-driver te verwijderen en de nieuwe te installeren.

Installing New USB Drivers
This version of WeatherLink contains version 4.28a of the USB drivers needed for the USB datalogger (product 6510USB). WeatherLink Version 5.7 and 5.6 shipped with version 4.28a and WeatherLink Version 5.5.1 shipped with version 4.20 of the USB drivers.
If you do not have a USB datalogger, you do not need to install the USB drivers.
This version (4.28a) of the drivers does not support 64-bit versions of Windows!
If you have NOT previously installed a USB driver for your USB datalogger, make sure you select to install the USB Drivers when you install WeatherLink and then click Yes when the installer asks you if you want to install the drivers.
Uninstalling the Old USB Drivers
If you have previously installed the previous version of the driver and have experienced problems with your USB connection, or if you want to update your driver on general principles, you will need to first un-install the old driver before you install the new driver. or before you install WeatherLink.
To uninstall the old USB driver, first open up the Device Manager. Depending on which version of Windows you have, you can get to the device manager either by right-clicking the "My Computer" desktop icon and selecting Properties (or opening the System icon on the control panel), opening the Hardware tab, and clicking on the Device manager button; or by right-clicking on the "My Computer" desktop icon, selecting Manage, and clicking on the Device Manager icon in the left hand window.
In the Device Manager, open the tree under the heading "Universal Serial Bus controllers". If you do not see an entry named "CP2101 USB Composite Device" or "CP210x USB Composite Device", plug in your WeatherLink USB datalogger to cause it to appear.
Double click on the device entry ("CP2101 USB Composite Device" or "CP210x USB Composite Device") to bring up the property page. Click on the "Driver" tab to view the driver version and date which should be one of these two values: Old driver 4.20.0.2700 3/11/2004, the new value should be 4.28.0.2700 12/16/2004.
If the driver version and date match the ones for the new driver, you are done. Otherwise, click the Uninstall button to uninstall the driver. Disconnect the USB datalogger so that Windows does not try to find a new driver for it. (If the Hardware Wizard launches, cancel out of it without loading a driver.)
To install the new drivers, run the program PreInstaller.exe that is located in the USB_Drivers_4.28a folder inside the WeatherLink program folder where you installed it. (The default is "C:WeatherLinkUSB_Drivers_4.28xPreInstaller.exe".) One way to do this is to click the Start menu and select Run. Then click the Browse... button navigate to and select the PreInstaller.exe file and click "Open". Click "OK" to launch the USB driver installer, and click "Install" to install the USB drivers.
