Maybe, maybe not.
Oh well,
I'm not looking for pci-card for classic macpro. I'm looking for reasonably priced usb hub. With the speed what should be the standard in 2020, 10Gbit/s, ie. usb3.1 gen2, and used for the next decade.
Or are you so funny that you suggest that I'll start to use some old cMP as an usb hub? Power consumption 200W it idle?
