MacPro early 2009 5.1 144.00 usb install question

as mentioned in https://github.com/dortania/OpenCore-Legacy-Patcher/issues/1021
it is suggested to use an usb hub for using keyboard & mouse.

i plan to workaround it by installing this card:

Chipset: Fresco Logic FL1100. PCIe x1 Gen 2.0 Port. Compliant with the USB 3.0 standard (Revision 1.0). Compatible with the USB 2.0 standard. Compatible with the xHCI Specification Revision 1.0. 2 USB 3.0 Type-A ports. Supports legacy USB functionalities. Two downstream ports support the following throughput speeds: SuperSpeed ​​(5 Gbps), High-Speed ​​(480 Mbps), Full-Speed ​​(12 Mbps), and Low-Speed ​​(1.5 Mbps). UASP mode (USB Attached SCSI Protocol). Up to 5 V / 3 A of power available via the USB 3.0 port. Easy installation: Plug-and-Play and Hot-Plug compatible.

do you think it may work?
