Problem Deploy Panda III Board

Hello,
I have a Problem to Deploy my new Panda III Board, it always hangs on:
"…Assemblies successfully deployed to device.
Restarting interpreter…
Attaching to device…
Waiting for device to initialize…"

and after that:
“The debugger engine thread has terminated unexpectedly with error ‘Could not reconnect to the debugging target after rebooting it.’.”

I use :
VS 2013
NETMF SDK 2016 R1
TinyCLR 4.3.8.0

I want to deploy a simple App:
while (true)
{
Debug.Print(Resources.GetString(Resources.StringResources.String1));
Thread.Sleep(1000);
}
Has anybody an Idea ? By the way is it right to use the NETMF Console Application for the Panda Board ?

@ CS5798 -

Are you using a hub usb?

Hi Dat,
yes and that is the problem. I test it now without
the Hub and it works. Strange I had never a problem with the ceberus board.
