Works fine with Win10 on a Gateway DX4850

I have a full size tower, but I really like that the FS-U4 can be used in a mini-tower PC. I am not using this for a power source; I have a powered USB hard drive attached. It installed flawlessly in the case, and Windows 10 recognized it at boot with no extra help. Data coming from a USB 2.0 hard drive via the mainboard port to the USB 3.0 hard drive is about 32MB/s (~320Mb/s) ... which is a lot faster than when the same USB 3.0 hard drive was connected to the USB 2.0 port. It can write about 131MB/s coming from the SATA C: hard drive to the USB 3.0 hard drive. The only complaint I could have, is that I wish it came with a 'Y-splitter' power cable. I have a 750W power supply, but the power connectors are limited. ----------2019/03/20---------- Bummer. Microsoft just upgraded me to Win 10 Version 10.0.18356 Build 18356 last week, and this is no longer working. I have uninstalled and re-installed vendor and Microsoft drivers, but cannot get to work any more. The USB xHCI Compliant Host Controller just shows a little yellow triangle in Device Manager, and the Reneasys driver only sticks around until reboot, then it gets replaced with the xHCI one. The explanation is very helpful: This device cannot start (Code 10).

works perfect with windows mixed reality lenovo headset but no front USB 3.0 ports

works great with WMR, I had been having trouble with at least two different brand usb cards including inatek and the gigabyte onboard usb 3.0 from etron was absolute garbage. DO NOT INSTALL THE DRIVERS, the renesas drivers or whatever they are called are for windows 7 an windows XP, do not install them on the most recent edition of windows 10. the card will work fine, even great on generic windows 10 drivers. if you do install the driver windows home portal will start giving you error 15's and you will have to completely uninstall mixed reality to fix it. this card has no front usb 3.0 port internal conncetors? Why? I guess to keep the cost down but I would have prefered to pay a little more to have front connections. keep in mind this has VERTICAL USB SLOTS, so if you have a tight metal case, you may have to squeeze or bend your usb cables to get them in.

Turn off WIN10 'Fast Start' and Hibernation Options.

This USB 3 card works as advertised. Make sure you turn off 'Fast Start,' or whatever WIN 10 is calling it this week. "Fast Start' really should be named "Faster, but not so smart start.' This option totally skips over this card, making it show as a non-starting product in Device Manager. Half the time items hooked to this didn't start. I started to think the card is bad, but when I turned off this 'Fast Start' option and the Hibernation option, the card was recognized and works.

Sometimes W10 will pick up the drivers...sometimes it won't for this card

I'd read that W10 would detect the hardware and auto install the drivers for it. Not so in my case. I think it depends on how old your machine is and what hardware you have. My machine is a good 10 years old, but it has an early iteration of an i7, with added memory to at least give me 8GB there. But it did turn out to have a working PCIe card slot, and this fit perfectly. Not my main machine but a side project to see how I can keep it running at a fairly high level. A couple notes: it showed up in Device Manager as an unknown device, and not under USB controllers. I tried installing the drivers straight from W10 but no dice. So I installed the drivers from the little cd included with purchase. It required a restart after that before finally detecting the brand name under USB controllers in Device Manager. So...you might need to ignore the troubleshooting tips in the included pamphlet instructions like I did...as it called for reseating the card after failure to detect as intended. In the end: seat the PCIe on your motherboard, then install the drivers off the cd, then reboot, then check and make sure it took in Device Manager (if your system doesn't detect it right away and install drivers from DM).

Fast and reliable

I ordered this card after having continuing problems with a prior usb plug in wifi card which dropped connections daily. Since I am using my high speed fiber network to receive and record off the air tv I have to have a reliable connection to prevent dropped programming. This card exceeded the expectations I had developed based on prior reviews. It installed without any glitches with windows supplied drivers and I routinely receive Wi Fi signals of 350Mbps to 650+Mbps from my Archer 3150 router based two rooms away from the PC.

Perfect for VFIO KVM setup!

Bought this for a VFIO KVM passthrough setup and it worked flawlessly out of the box. Just passed the IOMMU group through and my Windows 10 VM picked it up instantly and installed the required drivers. It uses the Renesas uPD720201 controller. Very happy that it doesn't require external power as that would've been a pain in my case. I've had all 4 ports populated at once (keyboard, mouse, USB DAC, and USB mic) and I had no issues with power delivery. Would recommend.

fixed an additional problem

story summary: crappy refurb computer that did not have USB 3. had to turn off USB hub every time computer turned on during boot process because it tried to boot from external HD that didn't have operating systems, and then turn the hub back on after a specific point. was not able to find a fix in BIOS or online. 2 or 3 years later got this USB 3 card. put it in. now computer can reboot or turn on without having to turn off USB hub. hopefully this review gets indexed by search engines in case others have this issue.

Reading speed of 116.1 MB/s and Writing speed of 106.9 MB/s

Currently the USB 3.0 Expansion Card (FS-U4L-Pro) is functionally good. With reading speed of 116.1 MB/s and writing speed of 106.9 MB/s, the card meets the standard USB 3.0 transferring speed. Low profile bracket is a plus for my computer internal ventilation. Another worthy consideration of buying this product is because it doesn’t need additional power supply. Windows 10 automatically recognizes the expansion card, so just install it on PCI-E x1 slot, then you can start using it.

Bought for 2U server to pass thru to VM

I picked this up to add 4 USB ports to a 2U server. I was looking for a low profile card with as many ports as possible. Changing to the low profile bracket is plenty easy, the fact the card draws power from the PCIe slot instead of a separate power adapter is great since most Enterprise servers don't have spare SATA or molex power. Works well, passed the chipset into a Win10 VM, no need to install drivers.

Absolute must have

This is an absolute necessity for any PC without 3.0 USB in today's technology. Plugged right into the pcie slot on motherboard without any problems. Windows 10 drivers had it working without the need for the installation disc. (Although I still used the installation disc) works great. Arrived quickly.
