Hi,

When I use an USB-hub and plug a DMXking dongle in it. During a show, I can't plug anything else in the USB-hub. When I do, QLC isn't responding anymore and few moments later the program crashes. All unsaved data is lost. (Maybe an auto-save function for V5?)
When I plug all devices in the hub before starting QLC, there is no problem. But when I unplug or plug another device, it happens.
Is there a way to solve this problem? Or is this because of device manager which is searching for the new devices?

I am using:
Windows 10 Pro
Microsoft Surface Pro 3 256GB
Only 1 USB connection (that's why I use a hub)
QLC 4.11.0

But this is something different. When I just have a midi device connected and no usb-hub, the program doesn't crash. Only when using an usb-hub.

Please test the latest test version here

I have added a button to enable/disable USB hotplugging. It's now disabled by default
