I've got it with XIM LINK:
Mouse is on mousepad with receiver built in and sends the signal to mousepad. Mousepad is plugged in PC.
I don't know if it's working without XIM LInk, so if you put the mouse pad directly in XIM Apex without PC. I don't know i f you need the Logitech G Hub software to work.
Maybe you can offer direct support @OBsIV.
Here you can understand the technology:
https://www.logitech.com/assets/65321/2/powerplay-wireless-charging-system.pdfSo the mouse sends the signal to the mousepad and the mousepad has the USB adapter and is plugged in. So you can load and play at the same time with the mouse. The signal isn't coming directly from mouse to USB, it's Mouse --> Mousepad --> USB --> XIM/PC.
