or
Two USB Type-A connectors. Up to 10Gbps data transfer speed, twice as fast as USB 3.0.Low Profile board. Include both Low Profile and Regular Size PCIe brackets. PCIe x4 card fits in any PCIe 2.0 or PCIe 3.0 x4 or x8 or x16 slot.Instead of taking 5V power directly from power supply, our design includes power switching regulator circuit that automatically converts 12V from PCIe bus or from 15-Pin SATA power to ensure sufficient 5V/2A bus power on each USB port.No driver installation is required on MacOS 10.9 to 10.10, and 10.12 and later (NOTE: macOS 10.11 in-box driver doesn't support ASMedia USB 3.1), Win10/8, Server 2012 and later; Linux 2.6.31 and later. Driver download is available for 32/64 bit Windows 7/Vista, and Windows Server 2008/2003.Built with ASMedia ASM1142. Fully RoHS compliant. Made in Taiwan.

Thanks for the reply. I should add that if I boot a Win10 VM everything works perfectly. So are you suggesting that I should be looking at a macOS USB speed issue? This is the card I used https://amzn.to/2QR2dxf .
Well let's look at the chips first. It's a bit confusing. The ASMedia 1142 is for type A/5 Gbps ports. However, it looks like the cards with 1 type C and 1 type A also use the 1142. The ASMedia 2142 is for type C 10Gbps. They both seem to come on cards designed for a PCIe x4 slot.
Those chips control 2 ports each and if you got a card with a 2142 you would need type C to type A adapters as well. The 1142 has great performance so I wouldn't necessarily avoid it even though the cards are older, since you just need type A connectivity.
So if you want the newest and best and money isn't so important, I would get a 2142-based card with two type C, and get Type C to Type A adapters. Such as:

and:

If you want to keep it simple and get a card with two Type A, something like:

Also note that they suggest using the built in Windows drivers and not installing the ASMedia driver, for UASP support. This may not be true with subsequent updates to their driver.
Hope that helps some. You may want to search dedicated VR forums as this has certainly come up before. You might want to try comparable ASMedia cards from lower priced manufacturers than Ableconn, that's up to you.
