Error in VISA Configure Serial Port

[wa5ycg]

Is there are way to NOT report the labview error -1073807343 when using the VISA Configure Serial Port VI.  In the case that the USB device is not plugged in I just need to know it and avoid the rest of the operation.  Instead I get this error and it halts operation even though there is no error VI in the code.

Sounds like you are not handling your errors and the automatic error handler is popping up.  You should be passing your errors along.  You can then look for that error and handle it somehow (clear it, skip over the rest of the code, etc.)
