Should I download a Windows® driver for the Cypress USB hub (CY7C65630/CY7C65620/CY7C65631/CY7C65621) in order to use it?
You do not need to download any specific driver for the USB hub device. The Cypress USB hub (CY7C65630/CY7C65620/CY7C65631/CY7C65621) uses the generic USB hub driver usbhub.sys that comes with Windows OS. The driver can be found at “C:\WINDOWS\system32\drivers.”
