Review on High-Speed USB 3.1 Gen 2 (10 Gbps) 2-Port Type C Expansion Card with Asmedia Chipset for Windows & Linux – PCI-E PCI Express 4X (2XType C) by Mason Gordon

OS: Windows 10 Education Installed in PCIe 2.0 x 16 slot on ASRock B450m/ac AMD AM4 Promontory motherboard. The 3.0 slot has a GTX 1080. It's a Matx build so it was a bit tight. It's probably an inch from the GPU and a few inches from the PSU case and very close to the phone's ports, but that was fine. It was such a small card that it fit in without directly touching anything or directly blocking fans. I doubt this will cause any airflow issues. The ONLY issue is that the clip doesn't sit flush with the case, but that's minor. On Windows, I was surprised to find that Device Manager didn't confirm anything about addressing, and Windows didn't tell me anything. I don't know exactly what it shows up in Device Manager. However, I connected a USB-C drive, Nintendo Switch and Samsung Galaxy S8 and was very satisfied. I haven't run any tests yet. The USB-C drive transferred files quickly, the Switch charged, and the Galaxy S8 recognized, charged, and approved file transfers instantly. Essentially plug and play. I didn't have to look for drivers. It also included a CD and a mount for the smaller case. Who has CD drives now? :PI bought a used card from Revain Warehouse. It costs about $16 after tax with Prime Shipping. It took a while to get here due to the pandemic but looks brand new. For the price I'm thrilled. Hopefully this works fine for a long time and I don't have any issues like some of the other reviewers.
