Crash after unplugging USB

Post by hutje » Thu Jul 06, 2017 2:05 pm

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.

powered USB-hub I hope? Otherwise you deplete the power capabilities of your computer...
All electric machines work on smoke... when the smoke escape from machines... they don't work anymore

Please test the latest test version here

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