SerialPort COM Port over RDP

I try to connect to an USB device which is accessible on Virtual COM Port X. Everything works fine (local). Now I'm using a RDP (remote desktop) session and try to connect to my device I don't get any response. RDP COM Port redirecting is activated. If I run:

SerialPort.GetPortNames()

on my RDP Session I will get the right port (in my case COM Port 9). Then i try to connect:

_port.Open();
_port.Write(buffer, offset, count);

I can see that my device (connected on my none RDP Session host) retreive some bytes (LED are blinking) but I never get any response/results.

If I try it local, everything works fine.

What I'm doing wrong?

Can you confirm if you are connecting to the device on the target PC not from the PC you are opening the remote desktop from?

Local Setup: Target_PC -> USB_Device = Works

Remote Setup: Other_PC -RDP-> Target_PC -> USB_Device = Should work
