USB PCI CARD - not enough power for logitech cameras

I was using a Mac Pro 2012 for video streaming, I have 4 cameras I was able to use the three USB ports in the back and the one on the front of the unit to power all my cameras and external hard drive.

Now I upgraded to a Mac Pro 2019 which only has 2 USB ports so I bought the following card

Once installed I see that the card does not recognize any cameras or hard drives, I will return the card but what do I do to have USB capability on this machine? Is there another card out there I can use???

Mac Pro, macOS 10.13

That setting first appears in Catalina. If you were running older, that would not be the solution.

Sonnet tech also says you need some beefy cables to run USB-Powered devices:

Really, so allowing this in Sec and Ext will give the card enough power to run my cameras?

Oops, what I wrote form memory is incorrect.

That card, unlike all others, intends to provide up to 7.5 Watts per USB port. Watts is Volt * Amps, at 5 Volts that is 1.5 Amps per slot, more than enough for most ordinary devices.

Does this card require a Driver? No but this:

footnote 4. Must authorize charging support kernal extension in Security and Privacy System Preferences. (Unlock, then allow.)
