HP Recommended
Product: HP Z8 G4

After upgrading the Front USB I/O module on my Z8 G4 from the entry level module to the Premium module with 2 USB-C ports (including purchasing the FIOP OcuLink cable ) I received a yellow warning in the USB Connector Managers section of Device Manager "UCM-UCSI ACPI Device Error 43". The Usb-C ports are working for mouse or keyboard inputs but video isn't being recognized and I don't have any device to test if the charging is working.. I have tried updating the driver, uninstalling the device, holding the power button down to clear the CMOS and reflashing the current BIOS, but the problem still persists. Also under the USB Connector Manager section in Device Manager there is a second entry of UCM-UCSI ACPI Device which is working normally and without any yellow warnings, I'm not sure if that is related to the Thunderbolt 3 card I already installed. Any help would be appreciated.
