Bought this when I needed an USB3 connection for an external backup drive. It worked well. I then upgraded my mobo to one that had USB 3 and didn't install this device. After a bit I noticed that my external drive would be disconnected and I would have...

Could be a problem if you don't want your USB 3 devices on all the time

Rosewill USB 3.0


works well with USB 2.0

Do not buy this card if you're going to use it on Widow 8.1. Was using it on USB 2.0 external drive but when I got a new USB 3.0 external drive no great speed improvements which was the reason why I bought this piece in the first place. Updated...

Works with Windows 10 Preview


For anyone concerned with future upgradeability, it works fine with the Windows 10 Preview just released. The driver is built into Win10 so it comes right up if you fresh install

Have to wait for final version of Win10

title says it don't waste your time, I checked to make sure my computer had the correct slots and correct everything. This is rare that I buy something that ends up in the trash, 35 years with computers I guess I can't always get things to work as they...

Works in OS X


Works in OS X, I installed a driver from Lacie and it works great. I did not give the card power and it still works. I assume this is because I am using a device with it's own power supply.

Works in Mac OS X 10.9 in my Mac Pro Early 2008! And it works at USB 3.0 Speed

Need to install a driver

works USB 2 drops USB 3


Apparently there are huge problems upgrading older USB 2 main boards to USB 3 - the tales of woe are all over the internet with many different chips, not just the NEC (Renesas) chip. It will be hit or miss as to whether your older main board will play...

none really since it constantly drops USB 3 devices. Completely drops off the computer in the middle of large file transfer at USB3. On the other hand USB 2 devices work fine - just what I needed - another 2 USB 2 ports

drops out when using USB 3 deveices

Not worth sending back


Renesas *IS* NEC Semiconductor for all intents and purposes. Just because YOU haven't heard of them doesn't mean they are a no-name, fly-by-night, garage operation. NEC had the first decent USB3 chip on the market and was the de facto standard for...

Cheap. Well known chip maker (despite what others seem to believe), works fine as yet another pair of USB2 ports, which I need like I need a couple more holes in my head

Comes up as USB3 capable in both Win7x64 and several Linux environments, but always falls back to USB2 speeds when I actually plug a USB3 device in. Tried several external drives, including a brand new 4TB MyBook. Tried every driver I could find, as...
