Is the card reader usb 3.0 or 2.0?

It claims 3.0 but the read speed is determined by the card you put in it more than the 3.0 USB. I get similar speeds on either bus.

The card in the unit determines where it is EITHER USB3.0 OR SATA. It is one or the other, NOT both.

It works with USB 2.0. I didn't notice a difference between using USB 3.0 and 2.0.

yes it is 2.0 but make sure your pcie 3.0 card is backward compatible not the motherboard. some newer card now a days are backward compatible.

Yes I am using this card reader with windows 8 kn two different computers with no prpblems at all. The card reader also works quickly and I am happy with it. I am using it on both usb 2 and 3 ports.

There are two cables coming out of the back of the unit and both need to be plugged in to the motherboard. The USB ports on the front of the unit are USB 3.0 but the card reader aspect is *only* USB 2.0 and that is why the second cable needs to be connected.

it should work with a USB 2.0. to figure out if it is a 2 or 3 you have to go to the control panel and look for the ports. right click on the port you are using and click properties. if your computer is more than a year old chances are it is a USB 2.0. the difference between the two is speed of transfer with 3.0 being faster.

The box only mentions USB 2.0. I would guess a USB 3.0 should be ok, just won't get the 3.0's speed rate for data.

it is 3.0 but it comes with a separate USB cable to provide power if your using USB 2.0, so in that case you will need 2 USB ports. BTW USB 2.0 and USB 3.0 are the exact same connector, USB 3.0 just provides more power.

This card reader employs a PCI-express card to provide USB 3.0--you cannot hook it up via a 20 pin header on your motherboard. It does require 2 USB 2.0 headers, and at least 1 SATA header. As for this other connection being compatible, I would have to refer you to your motherboard and device recommendations--Improperly coupling devices to your motherboard could irreparably damage both.

Go to control panel and click system, then click on device manager. Scroll to bottom for USB list...should show 2.0 3.0, etc. If u have the original owners manual for ur PC or laptop, that will also tell u.

Of course. USB 2.0 will never match 3.0 speed. When the drive worked read on 3 was at least 4 times faster

If no one has mentioned this if you have only USB 2.0 ports on your computer and you have a free PCIe slot you can purchase a USB 3.0 add-on card that will give your older USB 2.0 only computer USB 3.0 capability. Hope this helped some.

Dear Boomchikawahwah, We do not carry a USB 3 card reader at this time. We are sorry for the inconvenience. We really are not familiar with any that are available yet. Sincerely, Elago Design Support

This hub is USB 3.0 and backwards compatible with earlier versions of USB. It is plug and play with Windows 8.1 64 bit (which I run). Just plug it into a USB port, power it up and it works. The card you are running is irrelevant. It plugs into a USB port.

The newer model is actually cheaper for some unknown reason. As far as I can tell that is the only difference since USB 3.0 is backwards compatable with USB 2.0 ports.

The card reader and the 4 USB 2.0 ports on the device use the USB 2.0 from the motherboard. You will also need a 4 pin Molex to power the hub. The card reader might work without this. Also be aware the microSD and SD card slots cannot be used simultaneously. USB 3.0 ports on the motherboard are only required for the USB 3.0 ports.
