What does "Insufficient system resources exist to complete the requested service" mean when adding multiple Webcams?

You may receive the error message "Insufficient system resources exist to complete the requested service" when attempting to add multiple Webcams to vMix.
This error is sent to vMix by Windows and means that too many devices are sharing the same USB "bus".
 
To work around this issue, try the following:
 
1. Remove any external USB hubs from the system as these will likely prevent multiple webcams from working.
 
2. Connect the Webcams to USB ports as far from each other as possible, on laptops this means ports on the opposite sides of the laptop.
One some PCs ports are available in different colours, such as Blue, Red and Yellow, plug each webcam into a different colour for best results.
 
3. If the above does not work, plug the webcams into Blue USB 3 ports if possible, instead of the older Black USB 2 ports.
 
In most cases, a PC or Laptop may only be able to handle 2 Webcams at the moment so keep this in mind.
For more inputs, a capture card and video cameras will be required, a list of which can be found below:
