I have an Arduino Pico connected to MATLAB and I use Terminated (CR/LF) trigger to read the input. Each message is about 10 to 12 characters and they come in at random intervals of a few seconds but potentially as fast as a few ms apart. It works 99% of the time or so but I am losing some character packets. It appears that if I am also writing data to disk that USB packets get dropped more often. Is there a way to make sure data isn't lost?

You might have to share more details about your setup and your code.
Also, does there seem to be a relation between the interval and the chance of data loss?
