Hi Luka,
The MS HID driver will automatically install so you would need to delete it in Device Manager and select your own custom VISA driver. This can be done using LabView's VISA wizard utility that allows you to create your own USB raw device driver.
If you knew what the DLLs are in the HID driver you can also use it in LabVIEW by using a Call Library Function Node.
A job for a rainy day !
Possible if you have the time and inclination.

Can you use LabView to access HID devices? There are MS DLLs with functions that allow low level access. Once you can open it then you will need to send the correct commands to read temperature/humidity and then calibrate the readings. But opening the HID device would be the tricky part.
