The USB-CTR04 is directly connected through one of the usb ports to the RPi CM4. No other daq devices. All of the prerequisites are installed and this is the output of a few of the C library examples: Turns out that trying my application today yielded a connection. I did not change a single line but it seems to work as it should, thanks for the help regardless!

Hello! I am currently working on a deployment of an application through Qt creator that talks to a USB-CTR04 to send trigger signals to my other devices in the chain. I have been developing on a raspberry pi 4 using UL for Linux and Qt and everything is working great. However, when I try to deploy my application, the app fails to connect to the board. The library was linked (libuldaq.so.1.2.1), and I am receiving no crashes, however the board gives me an error code of 4 when I run the following line "ulConnectDaqDevice(daqDeviceHandle);" The board is found but a connection can not be made. This error only occurs on my deployed application, tested on multiple devices. Is there a configuration program I need to bring onto the deployed machine to configure the board the first time or other libraries I may be missing? Attached is the config.log received from the machine I deployed my application on. I tried rebuilding the libraries on the machine with the deployed app and had the same issue. config.log
