USB Serial Com Timeout after 10min running

[ArturG]

Hello, I'm using win10 enterprise version and running QNX in the virtualbox. My application uses Modbus RS485 through an USB-Serial by FTDI.
It happens that everything is running okay, but after 8~10minutes my serial communication stops. It seems there is a timeout after we start the virtualization.
Anyone knows if there is an configuration which I can do?

Did you check the energy saving settings for the USB device/port on your Windows host?

Hello Martin, yes it is disabled. I ran this application in others vm players, and the phenomena didn't happen.
I try to use others versions of virtualbox like 5.2.4 and the delay on serial port increased a lot... 40ms to 230 ms ...
There is something happen.
