Just got this, what is the deal with the two USB cables? One for Power, one for data? Do I need to use both?

Yes one is for power the other power/data. I am running the drive on the data cable only. It did not run from the HUB without both plugged in, so I plugged the data cable direct to my laptop and it works just fine without the power cable.

Yes, you need to use both but the problem is the driver because my Windows 8 HP, don´t recognize it and I must use some software to view Bluray movies.

I wondered the same thing when I got mine. I believe you are correct in saying one for power and one for data. I have always used both. You could just try one cable and see if it works. I thought I read in one of the reviews somewhere that with one cable blu ray didn't play right. You would just have to try it and see. Sorry I could't be more helpful.

Yes, that is the idea, and like the other answers say, you can probably get away with only using one. However, if you aren't using a USB hub, you should just play it safe and use both; I've had a hard drive with the same sort of setup that usually worked with just one cable, but it was right on the edge, and I had it cut out a couple times. If you are using a hub, it doesn't matter if you use both or not, they're generally capable of providing all available current up to 2.1 Amps through any single port.

Yes, one's for power, the other for data. Whether you need both depends on your computer. If you have a recent Mac or a PC with a high-power USB port (one that can provide 1100mA at 5V rather than the standard 500mA [USB 1.1/2] or 900mA [USB 3]) then you just need the one data cable. Otherwise, use both.

USB is for firmware updates which I have not tried. Power is only through the 4pin Xlr connector.

You need the cable also, one end has usb 2.0 input female, the other output Male or vice versa

One connector of the 2-connector Y-design only transports power not data. As a matter of fact I'm not aware of a cable that allows you to do that.

two cables are included...one for power, one for data.. ours was a seamless use with vista...

I guess that depends on the resources that you would be plugging into your usb's? Primarily I use them to monitor all of my Corsair hardware. I use a Asus Impact but I run into resource issues because I have two 4 drive USB hard drive towers. But I've not daisy-chain two.

You will need to buy one seperatly. I bought a PCI one but you could use a USB one as well

I'm aware that the drive works with both USB cables plugged in. However, since the choice is between using up an extra usb port and a usb extension cable (my laptop has exactly two ports: one on each side, so the default cable won't reach); buying a usb hub; or finding a power adapter that will work with the unit, I would prefer to have the extra power cable run to where the drive will "permanently" sit.

I'm using my USB connection to successfully power mine. I have not encountered any issues with this.

It has the second USB connector if additional power is needed but I am running it using just the main USB connector plugged in....No issues to speak of.

I'm not the seller, sorry. I'd suggest looking up some installation guides because it can be a little tricky I had to buy a powered USB hub when I got mine.

Power source is not USB. Comes with 12 VDC power adapter. Has two different data interfaces: USB 2.0 or eSATA. Use either one at a time, but not both. I have found the USB interface to be more reliable, although a bit slower, but not by much.

Yes. This cable is power and data wired. Be sure if you are getting cables for reasons other than charging your electronics, it must state that it is a data cable as well. This cable simply extends the USB port, so it is wired for both power and data.

Yes, I have done so on both of mine. Suggest a USB. If you add one internally the BIOS will "yell at you for having opened the chassis". Not a big deal to turn off but.... In any event, I have an internal on one and a USB on the other. Little or no difference in performance.

It depends on your computer. My lap top is the same as yours, one usb on each side. For me, this device works with one usb connected. THe second is for power inn the even it does not get the power needed.

It uses two USB ports to power micro USB devices like portable external hard disks or external DVD burners, so you have separate USB for data and power

Other answers are correct and also, each usb port "divides" the available "speed" amongst connected devices, so if you have 2 drives connected to one port at motherboard level, you will be splitting the available bus speed between the 2 devices (i.e. expect 1/2 bus speeds (real-life will be lower) from each device when connected/used at same time).
