does this use usb 3.0

No its 480mbps high speed 2.0. I like it as its easy to install and works with windows 7 and I have 3.0 on my motherboard and to tell the truth I copied several files from the computer hard drive to a external hard drive and several were over 1 GB and I could not see much difference in speed and the external drive is a USB 3.0. That card does everything I wanted it to do and I have no complaints, its worth the money.

It's a USB 2 card - you can plug in a USB 3 device but it will only operate at USB 2 speed.

No, it is a USB 2.0, however I purchased it for the internal Motherboard style USB slot. I needed an additional Internal USB and this card was a cheep option for that. It works great.

Unfortunately No. This card does not use, provide, or support USB 3.0... It only provides 7 USB 2.0/1.1/1.0 ports, but does so effortlessly with no conflicts or problems.

I believe it's only 2.0, at least with the version I purchased. There very possibly may be a newer version out. I put it in my Dell desktop to replace a burned out USB controller on the main board and it's worked flawlessly ever since.

Yes, it works perfectly with any usb 2.0 port, it just doesn't run as fast as a 3.0

This is USB 2.It will work with USB 3.0. I do not see any improvement in performance.

Some are and some are not. They usually indicate if a 3.0 is backwards compatible with 2.0 on the package or description. This particular USB 3.0 works with 2.0 as well and it has been working just well for me.

Yes, all USB3.0 flash drives are backwards compatible with 2,0 USB slots. Just with the slower speed.

The card reader does not use USB 3.0; card reader connects to the USB 2.0 on the motherboard. Only the USB 3.0 ports use USB 3.0.

No, It needs to use USB3.0 for the speed, it will not work in a USB 2.0 port.

No, it has a USB 3.0 connector which is downward compatible with USB 2.0. It comes with a USB 3.0 cable.

It works with USB 2.0 at 2.0 speed. But its worth it because of the future proofing aspect. 3.0 is much much faster. Hope i helped.

My new lap top recognizes it as USB 3 but my older PC does not. Their customer service was very helpful but in the end I returned it as I wanted it for my PC and it did not work as 3.0 with that computer.

USB 3 is backward compatible with USB 2. You just won't see the speed benefit of USB 3

Not sure, however I looked online and I think it only works with USB 3.0 port.

I only have usb 2.0 on the computer I upgraded and it worked fine. most (maybe all) devices that work with usb 3.0 will also work with 2.0.

Mine came with what was described as a USB 3.0 cable. I don't have a USB 3.0 port, so I plugged it into one of my USB 2 ports, and it works just fine. I hope this is helpful to you.

Yes. USB 2.0 devices work in USB 3.0 ports - they just aren't making full use of the fast transfer rate.
