Only one controller testable when 2 or more connected.


When using Toolbox to test gaming controllers, if two or more controllers are connected to the system, only one is testable.


There is a known bug preventing Toolbox from enumerating and testing multiple gaming controllers connected to a single system.


Connect each controller, one at a time and run diagnostics. The most effective way is to do the following:

  1. Connect controller A to the system
  2. Open Toolbox and test the device
  3. Close Toolbox
  4. Disconnect controller A and connect controller B
  5. Repeat steps until all controllers are tested.

We are currently working on resolving this issue in a future update to Toolbox for Windows.
