SIV64X and CL4 USB Driver package

Welcome to the forum and for the original H80i then you don't need the buggy Corsair SIUSBXP drivers to be installed.

When you look at Link Devices there should be a Corsair Integrated USB Bridge which is the H80i and first Device Plug and Play ID will start HID\VID_1B1C&PID_ so it a HID device and uses the standard windows HID driver.

The Corsair driver package is only needed when the first Device Plug and Play ID starts USB\VID_1B1C&PID_ which makes it a USB device. These devices are also listed in the Device Manager USB section rather than the HID section.

You could also check the IDs on Link Export which will also report which devices are connected to the bridge channels. Below you should see the H80iGT is a USB device so does need the Corsair driver.
