Review: The answer to my USB3 prayers! - Finally a card that works! This is my 4th (!) USB-3 card, and the first one to work AS IT SHOULD. I installed it into a 9-year-old Dell Precision T5400 desktop. It works like a dream - very stable, doesn't cut off in mid-transmission nor throws any other surprises. It is all to do with the fact that this card (Model PEXUSB3S44V) is a 'quad bus' card - it has 4 separate chips (4x Renesas [NEC] uDP720201) and 4 separate large capacitors - one for each USB port. The cheaper cards have only one chip shared between 4 USB ports, and this causes trouble. In case of my Dell I had power issues all the time with other cards - disconnecting drives, cutting in mid transfer etc. This one just works fine and in spite of the limitations of my old motherboard I get speeds up to 320 MB/s through this card (between SSDs inside the desktop and fast external RAIDs via this USB3 card). Optional (but absolutely recommended!) power connection to the card can be done by either a SATA-style power connector or older type MOLEX-type. The card then delivers up to 900mA of 5V current per port - sufficient even for my power hungry 2TB WD Passport (USB3). Be warned though about USB2 devices - the card only gives them 500mA per port, and my old disks require more power (via a splitter cable) from another port (can be USB2). It is an expensive card, but for me worth every penny. [One more comment: if you have a Dell like mine, avoid USB3 cards based on VIA 800 (or VLI) chip - this machine is 'allergic' to them, but Renesas 720201 works fine.]
Review: 4 Elgato Facecams plugged into this card, worked perfectly! - Found out about this card and grabbed it for an event that required four camera feeds. This worked perfectly - I had four Elgato Facecams plugged in, one per port and each using a 5m long USB A->C Cable. No issues at all over the 12+ hours it was all set up for. Important to note, you will have to make sure that you've got a PCIe x4 slot (and that it's actually running at x4 speeds, check your motherboard manual!) and power it with the SATA (or if you've got no other choice, Molex) power cable. If your PC supports it then this will most likely solve any USB power/bandwidth related issues you're running into!

## Questions & Answers

**Q: Does it come with an internal power cable?**
A: I’m pretty sure mine didn’t, but I didn’t need one anyway.

**Q: Do you need to plugin the power via molex or sata connector at the rear or will the card work without said power?**
A: I've run mine from the molex power connector. I'd also add to David Neal's answer neither my HP z800s or z400s will run this card. Did work in the older HP xw8600.

**Q: How many usb endpoints does this controller add?**
A: The PEXUSB3S44V has 4 USB 3.0 ports with each port having its own Renesas µPD720202 USB 3.0 controller. This controller supports xHCI and provides 96 endpoints. So in total, the card provides 384 endpoints, 96 per port.
Matt, StarTech.com Support

**Q: Can it handle 3 usb 2.0 webcams without any issues or loss of data?**
A: Since each port has it's own controller it should be able to. It handles Oculus Rift without any issues.

### ⭐⭐⭐⭐⭐ 4 Elgato Facecams plugged into this card, worked perfectly!
*by M***T on 15 March 2023*

Found out about this card and grabbed it for an event that required four camera feeds.

### ⭐ Very Poor Compatibility
*by G***N on 23 May 2018*

I couldn't get this to work with either Linux or Windows, most likely due to driver compatibility issues. On Windows, the USB host device fails to initialize and returns a Code 10 error. On Linux the driver loads seemingly without problems, but the connected USB devices don't appear. If you specifically need a multi-bus USB adapter, e.g. for passing different ports to different virtual machines, get the Sonnet USB3-PRO-4PM-E. It may be more expensive, but unlike this card, the Sonnet just worked for me out of the box on both Windows and Linux.
