FebSmart 4 Ports Superspeed 5Gbps USB 3.0 PCI Express Expansion Card for Windows 11, 10, 8.x, 7, Vista, XP Desktop PCs, Built in Self-Powered Technology, No Need Additional Power Supply (FS-U4-Pro)

works as directed plug and play no need to install drivers

It didn't work in the first PCI-E slot, only charged didn't recognize phone or other device. Checked Device Manager, card was NOT in there so I tried another PCI-E slot and it registered in Device Manager and recognizes devices now. Works without drivers in Windows 10 and it works PERFECT so far. Thanks for keeping my old Pc alive and useful! Updated 9/4/21 After two months it's still working fine. I was very worried about it dying suddenly like in other reviews but only problem has been two failures that required reboot. Card stopped working while being used with no warning. No system crash, just every card on device no longer showed up. Required a reboot and worked fine after that. Updated 10/10/21 The crashes seem to be caused by multiple access demands on the USB card. If you try to play media on two drives at one time you might freeze it up requiring reboot. Otherwise everything is still okay. Updated 2/08/22 the crashes are DEFINITELY caused by multiple calls to the card causing it to overheat and crash. I was using my phone on one USB, playing music on another USB and looking around in a third USB when the crash occurred. My power supply is 800 watt, it is NOT my power supply it is the cards limited capacity to hold a current that causes a fail. An otherwise PERFECT piece of machinery that should have been shop tested more with a greater capacitor.

Easy to install and seems to be working well but only time will tell. Powered up using PCIe slot- no aditional power source was required.

I bought this card to separate my Valve Index VR headset from the USB 3.0 host controller on my motherboard, as the controller on my Aorus AX-370-Gaming 5 motherboard would always get overloaded with devices and cause the camera pass through on the Index to stop working (Or maybe it just wasn't powerful enough, or didn't have enough "USB lanes" or something, I'm not really that technical). I had the same issue on my HTC Vive, the camera wouldn't connect or function at all but the headset tracking itself would be fine. I temporarily solved the issue for my HTC Vive by plugging it into a USB 2.0 port on the front of my motherboard, so it would use the 2.0 Host Controller instead of the partially functioning 3.0 one, but that sucked because I had a cable running from the back to the front. The Index uses a lot more USB bandwidth, especially with two cameras instead of one on the headset, so it can't run on USB 2.0, and the cable wasn't long enough to reach from the split point at the back all the way to the front of my case. I bought this card to add another USB controller and alleviate the problem. Packaging was simple, came with a driver disk and the card. I read that most people were getting it to function plug and play just by slotting it in, so I did that with a PCIE-1x slot on my motherboard. However, I couldn't get it to work, it kept showing an error code 10 in Device Manager saying "This device failed to start." I tried installing the drivers on the disk and rebooting but nothing changed. Eventually, I decided to move it a slot down from the PCIE-1x slot below my GPU to an open PCIE-8x slot, just to see if anything would change. On next boot it was there and recognized right away, so I just called it good. Perhaps it was just that it wasn't seated correctly at first, or maybe it was because the slot itself is bad. I had a WiFi card plugged into that slot previously though, and that worked fine, so who knows. Maybe re-installing the card caused the drivers to initialize better. I'll never know. However, now that it's working the card is functioning great and the Index has no problems functioning from the ports provided, and the camera(s) on my Valve Index work now too.

Seamless desktop upgrade. Who doesn't need more USB Ports? I added this card to a Windows 11 machine that had far too few USB ports, and the installation couldn’t have been easier. No extra power supply hookup was needed—the card truly is self-powered, and it was recognized immediately on boot. Within minutes, I had four extra USB 3.0 ports ready to use. Performance has been excellent. Transfers to external SSDs and large capacity flash drives are fast and steady, right in line with what you’d expect from 5Gbps USB 3.0. I’ve tested it with portable hard drives, webcams, printers, and even bus-powered hubs, and all ran smoothly without glitches or power drops. The ports are well-spaced, so even bulkier devices don’t block one another, which is a small but thoughtful detail. The build quality also stands out—it feels sturdy once seated in the PCIe slot, and I didn’t notice any wobble or looseness. One small tip: make sure you seat it firmly and give the drivers a minute to install automatically. For older Windows versions, you might need the included driver disc, but in my case Windows 11 handled everything itself. I also appreciate that the card runs cool; even after long file transfers, it never gave off noticeable heat. That speaks to good design and efficiency, since some cheaper cards can run hot or become unstable. Bottom line: A reliable, plug-and-play solution that expands your USB capacity with speed and stability—well worth it if your desktop is short on ports.

Although I can't boot from the server (due to the server not being able to see any usb3), it works as advertised and have several things connected to it.

the on card power supplies radiate severe noise affecting radio and TV nearby the transfer rate is fine but the power supplies had to be modified to stop RFI to TVs and radio. This card is only suitable to those who what their doing !!

work fine

Goes in to any available PCIe slot in and works. What more needs to be said?

Works great my USB controller onboard died. I have my Blue yeti Nao, Steelseries mouse and wireless headset, works great looks great with the black PCB
