Acer Iconia W511 - USB UART problem

Hi.

 

I'm trying to install/use a program, which is communicating with a datalogger over a USB UART serial connection. After the program is installed I'm able to see the device under devices (Port COM & LPT (COM8)).

 

But when I try to communicate with the device from within the program, I receive an error message "Cannot open COM-port", followed by this error: screen dump.

 

Is there anyone who knows, whether there are any security restrictions etc, attached to the USB ports.

 

 

Regards

/Henning
