USB/Virtual Serial Port - No Data Read & No Errors

I have a problem reading data from the STEVAL-MKI005V1 development board for the LIS3LV02DL accelerometer.
It's a USB/virtual serial port connection to the PC. I started out testing the connection with hyper terminal, which worked. I even changed the COM# settings (i.e. 2, 3, and 8) and still everything works. However, once I try this in Labview, I do not get any data read in. I also do not get an error. I do get a status code, 1073676294, which I've learned is ok. I've tried numerous things to get this to work.
I first started with a simple write then read. I'm now configuring and opening the port, writing a command, waiting a certain amount of time to read, reading data, and then closing the port. I'm also using the "number of bytes at serial port" option from a property node for the byte count on the VISA read.
I've done this before with other serial devices; albeit, not a USB/virtual serial port connection.
Maybe it's a USB/virtual serial port thing?!?!?!?!
Any help is greatly appreciated.
Dave
