Hi @jsulm ; the application is a windows based application which is build using QT with MSVC and the application is working quiet well in all PC , laptop and Surface Pro tablet with intel processor (other config was not used) but the application is crashing in surface 10 pro with ultra series intel processor and process are taking drastic time compared to it working in other systems . The application is misbehaving as well . Could you please help me out how to diagnose what the issue might be actually .

@DeepakD If your application is crashing then first thing to do is to run it in debugger to see where and why it is crashing.
"process are taking drastic time compared to it working in other systems" - what does this mean?
"The application is misbehaving as well" - this does not tell much. -
Hi @jsulm , I was able to do few analysis and saw that the application is not able to connect to the COM Ports when using a USB hub ; ie I am using QSerial to detect and connect to ports but ; when I am using a USB hub the application is not connecting to the system . Any idea on this misbehavior .

Hi just a guess but maybe USB serial ports are turned off in the UEFI

@DeepakD Please provide more details!
Do you use QSerialPort? If so do you have error handling and did you check what errors you get (https://doc.qt.io/qt-6/qserialport.html#errorOccurred , https://doc.qt.io/qt-6/qserialport.html#error-prop)?
