I have a VR headset that needs a USB type C port. My PC has only USB A ports. So as a workaround I tried several USB C to A adapters. None worked. I then tried a few PCI host adapters and they didn't work. Usually, after installing the adapter, it killed my video. Well, I was just about to give up, but thought I’d try one more PCI card. This one actually worked!

Color: 1x USB-A + 1x USB-C [ASM3142]
This is my initial "day one" review; I might update it after some months of usage. I got this card, despite cheaper but feature-identical alternatives, because this was is known-compatible with macOS. In my case, it worked right out of the box without any driver installations or other issues. Installation wasn't trivial, but that's due to Apple, not any problem with this card. The Mac Pro Mid 2010 (5,1) has no readily accessible SATA headers and cables coming off the motherboard, but this card needs SATA power. So, I had to get into the optical drive part of the case, undo the combined SATA data/power connector from one of them; run a SATA data extension from the data half of that back to the ODD; use a SATA power Y splitter, and connect half of that back to the ODD, then run the other half into the main section of the case, and use a SATA power extension to reach my new USB 3 card. It's a bit Rube Goldberg. Put the machine back together, connected a USB-C hub/dock that I ordered to the card's C port, and connected my 5-disk external USB 3 enclosure to the USB-A port on the card. Fired up the machine, got right to desktop without any kind of delay, and every device is showing up exactly as it should (so, 6 drives total that were formerly on USB 2.0 are now through USB 3 A/C). My aging but rather over-powered 12-core, 64 MB RAM Mac just got a new lease on life, especially now that I'm booting off an SSD, and have my main game and other "monster" apps that load a lot of data on another SSD. It was painful to be using USB 2 for external storage (like several minutes to copy over a single movie). WAY faster now. I do not expect I'll get the theoretical maximum of 10 Gb/s, but am expecting over 5. Will try to set up some controlled benchmarking of random and sequential reads and writes in different circumstances (from/to my boot SSD, from/to an internal 7200 RPM HDD, from/to another external HDD drive attached to the same card, etc.). Might test some app stuff, like speed to reload a suspended VM. And I should get another SSD and see how it does when mediated by this card.

I'm upgrading my Mac Pro (early 2009) because it has been the best machine I've ever worked on. But I needed faster USB. This card was not hard to install and it worked first time. I'm still booting into OS X.9.5 (Mavericks) so I didn't have to worry about any issues with El Capitain. That said, I have a duo boot system on my computer which does contain El Capitain. Just to be sure, I found some instructions on disabling the SIP in El Capitain (even though I rarely boot into that OS). I may hand not needed to do that (disable SIP in el Capitain) but I could never find any instructions on installing this card when you have a duo boot system. Anyway - I recommend this hub.

I purchased two models of this card, but Amazon will not let me leave two different reviews, so I'm averaging the reviews to 3, but please read on for details. I'd been having a hard time finding a PCIe USB-C card that works well with my Logitech StreamCam. I purchased several cards, and multiple of them did not work well. The StreamCam would either show up as a USB 2 device and not be able to do 60fps, or experience other weird problems that slowed the frame rate down to 5fps at 1080p, leaving lots of USB, v42l, and alsa kernel messages in dmesg. The camera works fine with a laptop that has built-in USB-C, and also works fine in a USB 3.0 port of my desktop using a USB-C female to USB-A male adapter, but I wanted to plug it straight in. Out of the first three cards that I'd tried, the version of this card with the internal USB-C header actually worked! I'm using this with a define R6 USB-C case, and it makes the USB-C port on my case work. Not great for charging (Ampere on my Pixel 3 reports ~700 mA charging rate), but seems to work with the StreamCam using Arch linux on an Asrock EPYCD8-2T motherboard. Maybe my one complaint is that the headers face left, so you basically need to leave an empty PCIe slot to the left of this card. Excited about this success, I decided to buy the model of this card that has two external USB-C ports, even though it was more expensive than the others I'd tried. Unfortunately, the card with external USB-C ports was the worst of the bunch. Not only does it not work with the StreamCam, it actually destabilizes the whole USB subsystem. Even if I don't plug anything into the card, just having it in my machine makes the camera not work well in my motherboard's built-in USB-A ports! So what to conclude? Maybe there is poor quality control, or maybe one model is better than the other. However, I'm going to send the card with external ports back.
