Disconnected from software

Hi all, I have made a some modifications in my rig (from VR to triple screen) and yesterday when I switched on everything is ok except my Simu2 that is disconnected in the software. Who has an idea ? Thanks !!

This means that the device is not powered on, or that the USB connection is not working. Is it visible in the Devices screen in Windows?

It’s OK now ! Thanks !!!
