Not many of you know the Windows Kits SDK has a USB Viewer which will allow you to view all of your USB hubs and devices.
Download the SDK
Follow these instructions to install the USB Viewer, then go to "C:\Program Files (x86)\Windows Kits\10\Debuggers\x64\" and run USBView.Exe
As some of you know, the X55 and X56 can develop ghosting if the USB Hub has too many devices on it, and this utility will allow you to see how your USB devices are being used.
The optimum goal is to have your HOTAS on a USB Hub by itself, but barring that, the USB Hub with the least number of devices.
To use this software, once opened, it will display your current USB configuration. Manually move your HOTAS USB connectors to different USB 2.0 Ports and hit the REFRESH button under OPTIONS. Continue to move your HOTAS USB connectors until you have them on a hub with the fewest devices.
Keep in mind that both the X55 and X56 are USB 2.0 compatible and should be plugged into a USB 2.0 Hub on the front or back of your computer. Plugging them into a USB 3.1/2 Hub is not recommended, if ghosting is an issue. As well, powered hubs are really not needed for input controllers. The LED's are extremely low power devices.
