USB RAW device freezes my LabView and Matlab program

[PK2015]

Hello everyone,

I am trying to figure out if I am the only one facing this problem. I created NI VISA driver for my HID device. It was working fine but now as soon as this device is connected to the computer and I try to work with it on LabView, the program closes. same thing with MAX, it crashes. So I wanted to see if I would get any luck in Matlab. As soon as I enetered the Resource Name, Matlab closed as well. I am not sure what is the problem. I never encountered this problem before. Someone please help.

You should use the HID driver instead of trying to make your own with VISA. In general, the wizard should not be used when you already have a driver, especially HID.

Hi Dennis,

But how would I communicate it with LabView? It was working fine earlier. It is just recently that I am having problems.

How was it working fine? You said that as soon you connected it, MAX closed. You can use the call library function node.
