What functions? What kind of data? Which function is returning a timeout error?
Please post your VI. It's impossible to help without know what you're dealing with.
Regards.

Hello,
Here is a VI where I test USB, I send a data a form of string, the error is in the "VISA Get USB Interrupt Data" sometimes his works well and sometimes I have "Error -1073807339 occurred at VISA Wait on Event in essaiUSB.vi".

This error occurs because the timeout expired before operation completed.
Did you try to increase the timeout?
By the way, an advice: close the serial port outside the main loop. It's better.
Regards.
