What if it does not work with my motherboard or my mouse?

Put the main PC cable in a port on the back of your motherboard first. Front and top ports can work, but they go through a cable inside the case and can cause dropouts, so use a rear port. Most mice work, wired or wireless with their own USB receiver, but not every one, and Bluetooth does not go through. Check the COM port number and baud rate match what your software expects. Still nothing? Open a ticket in Discord with your motherboard and mouse model. If the unit is faulty, the three months of warranty cover it.
