StarTech.com 4 Port USB 3.0 PCIe Card w/ 4 Dedicated 5Gbps Channels (USB 3.2 Gen 1) - UASP - SATA / LP4 Power - PCI Express Adapter Card (PEXUSB3S44V)

I'm using this with 3 RTL-SDR and 1 RSP-1A software defined radios and the sdrtrunk program that allows me to receive trunked digital public service radio broadcasts. The USB ports built into my motherboard could not handle the large amount of data being passed thru the ports when listening to multiple P25 and DMR trunked systems at the same time causing the program to crash. This card seems to have fixed this issue and the program no longer crashes. I plugged the card into a PCIE X4 slot to maximize dataflow. I have an older Antec tower case. Unlike other reviewers I had no physical clearance problems with the USB ports when plugging cables into the device.

This product came recommended through a few YouTube videos and some online VR forums. I was having problems running more than two sensors with my current usb 3.0 5 port card.. and as it turned out, even though there were 5 ports, only two controllers so there was always a conflict. This card absolutely solved my issue because each port has its own controller so it allowed all my room sensors to run at full speed usb 3.0 capacity. For refer, I am using a 3 sensor setup with an Oculus Rift CV1 setup, two up front on either side of my tv in my living room, and one on the back wall in the center facing down. I played for about two hours to test, and never lost connectivity with any of the sensors. Well worth the price paid to have all my equipment work as it should!

I'm going to be installing my fourth of this card because the first three all failed. I'm hoping this next card does the trick because when this card works, it works incredibly well and is exactly what it's advertised to be. Having four dedicated USB controllers in a single card really helps in certain environments. Basically, what seems to happen is the controllers just burn out and stop passing data. The card will still pass power to your devices but if you try to poll the ports you end up getting errors. And my experience with three separate cards, the issues don't start until about a month or two in and then the ports die one by one over a period of another four weeks. I primarily use this card because VR comes with a lot of USB bandwidth issues with the number of devices that are required for a full body kit. Running SteamVR diagnostics shows the ports come up as "general failure". I've had this happen now with three cards in a row and it seems like there's a couple of other reviews where this has happened as well. Support has been fantastic as they typically just tend to swap the card out but since I've had so many fail now they're trying to point the finger at me (even though nothing else in my system is having even remotely similar issues.) Depending on how support continues and if the next card actually has some staying power I'll update my review.

I tried 3 other less expensive PCIE to USB cards and they all had issues with drivers, throughput, or both! This card just works and really does deliver bandwidth! It also handles multiple hubs and high power devices perfectly! 0 drop outs, 0 latency issues, instantly recognizes anything plugged in! It also has better build quality with the vertical ports - they aren't obstructed by different cases like some other cards I tried! I don't know why I bother with other brands - I always end up back with StarTech. It also has 2 standards for providing power instead of just 1 odd one (floppy power on one that I tried). I highly recommend this card!

I have an old HP xw9400 workstation without any USB3 ports. I bought this card to provide some and because it was recommended by a co-worker who had tried it out on an HP DL380 server. But there seems to be some incompatibility between this card and the above workstation: I only got 3 out of the 4 ports responding. There were three free PCIe slots available, so I tried the other slots with no improvement. Assuming that the card was defective, I notified Amazon, and they sent me a second one - which was worse: only two out of the 4 ports responding. I put the original card in as well and tried plugging in a USB3 thumb drive in each port: all 4 ports on both cards were working! I took the second card out: back to 3 out of 4 working. That's where I am right now, since I sent the replacement back. The fact that all four ports worked in one configuration shows that the card is perhaps not defective, but it is certainly flaky. Caveat emptor, particularly if your machine is old (but if your machine is newer, you probably don't need this card anyway). Besides that, I second the common concern of the orientation of the ports: I understand that they wanted the card to fit half-height boxes with the shorter bracket and orienting the ports perpendicular to the long dimension of the bracket was the only way to accomplish that, but as others have noted, the width of the opening is just enough to accomodate a USB plug, so any misalignment of the card in the opening makes it impossible to plug in anything. The technique I used to avoid that problem was to plug in a USB cable to the top port (the one farthest away from the PCIe slot) while the card was not tightened down completely: then screwing it down (or latching it down as in my case) prevents it from getting out of alignment and you can plug in to the other ports with no problems. EDIT (2022): My (very old) xw9400 finally gave up the ghost and I replaced it with a (merely old) Z840. I moved the card to the "new" computer and it all works as it should. I guess there was some incompaitibility with the old machine. Extra star added to the rating.

Bought this to run a four-sensor Oculus Rift setup. Was sick of messing around with motherboard USB slots, getting 2.0 connections even on 3.0 ports, etc. - and as I hoped, this card instantly solved all that. Now getting full-speed 3.0 performance from all four sensors with no inconsistencies or problems of any kind. Pricey, but worth it if you want the best. Definitely easier and more reliable than getting a cheaper expansion card and splitting your sensors between that and the motherboard ports. TIPS: - Works plug-n-play with Windows 10 native drivers. I've heard others say the manufacturer drivers make things worse not better, so I never tried. Stick with the natives. - Make sure you have a spare x4-speed PCIe slot on your motherboard, which is the full bandwidth this card uses. Note that this is not necessarily the same as a x4-SIZE slot - check your motherboard manual to find out what speed each slot offers and whether it steals bandwidth from other slots. My MB (like many) has a bunch of x4-sized slots that only run at x1 speed, which would bottleneck this card and defeat the purpose - I had to plug it into the third x16-size slot, which runs at x4 speed. MINOR ISSUES: - Plugging USB cables into the horizontal ports is a very tight fit through the opening for the expansion slot, at least in my case (Thermaltake X5). It's not a problem for me since my Oculus sensors are permanently connected to this card, but might not be great if you plan to use this for stuff that you are plugging and unplugging regularly. - The small heatsink on my card was attached very sloppily - visibly on a bit of an angle, not straight and flush with the card. Still makes full contact with the chip underneath so there's no functional issue at all, and I may have just gotten a one-in-a-million bad draw. Was slightly disappointing for such a high-end card, but not enough so that I'd bother returning it for a replacement.

Très bon produit, depuis que je l'ai installé je n'ai plus de soucis de connexion sur mon oculus rift. Facile d'installation, bien prendre les pilotes Windows. Par contre sur le port PCI Express 4x le produit n'était pas bien reconnus. Je l'ai mis sur le PCI Express 8x (pour du 4x) et la tout à bien fonctionné. Je recommande pour ceux qui ont des problèmes avec l'oculus.

Mal diseñada en cuanto al slot y los puertos Usb. Hay que recortar el slot trasero de la caja para que permita la conexión de los buses. Los drivers para el 7 ni pa'tras, sin actualizaciones. El 8.1 la aceptó con genéricos de WU, que no regulan fino las tensiones provocando un uso máximo de 2 HDD de 2,5", ya que con un tercero, empieza el caos enumerador. No es recomendable y mucho menos por ese precio.

Habe das Produkt nach vielen Stunden Foren-Suche für einen bestimmten Zweck gekauft: Oculus-Rift-VR! Problem: die USB-Anschlüsse am Standard-PC arbeiten mehr oder minder über einen, vielleicht zwei HOST-Kontroller. Das - muss nicht immer - hat bei mir aber (aktuelles ASUS-Mainboard) zu Problemen geführt, da ich eine Menge USB-Anschlüsse nutze: Yoke-System, Pedals, WEB-Cam, Maus, Tastatur, 2x Drucker, Ext. Speichermedien, USB Sound-System und dergleichen mehr. Das kann nicht funktionieren, da die Oculus mit 2 + 1 Sensoren eine Menge eigener Bandbreite fordert. Der Kontroller eingebaut verrichtet seinen Dienst einwandfrei. Habe keinerlei Probleme mehr mit der Oculus Rift. Einzig der 3. Sensor muss definitiv an einen USB 2 Port - sonst meckert das Oculus-Installationsprogramm. Hier muss Oculus noch deutlich nachbessern - aber das ist ein anderes Thema. Auch alle anderen benannten Komponenten über die vorhandenen Standard-USB 3.1/3.0/2.x verrichten ihren Dienst nun ebenfalls ohne Beanstandung - sind von der Oculus entlastet. Es gibt noch ein deutlich günstigeres 4-Port-Modell von Startech mit 2 HOST, vielleicht hat jemand damit Erfahrung? Ich wollte einfach nur keine Kompromisse eingehen und hab das ganz große Modell (Forenempfehlung) bestellt. Wer das Geld dazu hat - ich kann dieses Produkt für die erwähnten Probleme mit der Oculus-Rift ohne Bedingung empfehlen. Nicht notwendig ist nach meiner Erfahrung die Installation der Startech eigenen Treiber. Zwar rät der Hersteller zur Installation, um die volle Leistung ausnutzen zu können, aber in meinem Fall (und Forenbeiträge bestätigten das) funktionieren die High Tech USB Ports mit den original Windows Treibern. Ich musste die Hersteller-Treiber wieder de-installieren, da inkompatibel mit meinem System. "Brille" geht auch so jetzt einwandfrei.

Couldn’t get all 4 ports working, randomly, only 2-3 ports were detected. Have tried re-seating the card, plugging in the data power, also tried the drivers online. Also be warned due to the vertical arrangement of the ports, your case might not fit.
