Thank you,

My C# app, analyzes data on various RS485 devices in parallel.
Connect devices to a USB port through a converter RS485/USB.
This configuration only analyzes the data. I need a person to turn ON and OFF the devices.
I'm extending the functionality of my application.
First, we put a USB device that will turn ON and turn OFF the devices.
The turn ON/OFF function is related to a USB PORT and Reading function is related to another USB/SERIAL PORT.
So I need to know how to send command to 2 or more USB PORT at the same time.

Hello, I took to resolve.
After studying all that you indicated me; I went deep inside; solved thus:
Create Methods for each USB and call this Methods in queue.

Now this works, however when exiting the app, continue with the message that the app is running in VS2010 Ultimate!
