A:
Assuming your mouse is operational, the issue is not the trackball but with your Lenovo computer.
I would remove any USB Devices connected to your computer, then uninstall any USB device drivers (first) then uninstall all of the USB Controllers, Hubs etc. then reboot, and Windows 10 should automatically install the USB Host controller. If it had a problem installing the Host controllers, then go to the Lenovo website and find out if Lenovo had its own Host controllers for USB. If so, download and install.
