Please clearify the term #USB how and why are they different from each other. I have seen them listed as 1, 2 and 3
1138485
the USB number (1.0, 2.0, 3.0) refers to the transfer rate (by generation of the universal serial bus) with 1.0 being oldest / slowest.
1138486
The number of the USB refers to the transfer speed. USB 1.0 is the slowest, and almost never used anymore. USB 2.0 is the most common and most devices are gauged to operate at USB 2.0 speed.The newest USB is USB 3.0, and not many devices other than flash drives and some external hard drives are using it. I hope this clarifies it a bit.

Thank you for your interest in our products. The main difference between the 2 versions are as follow: 4 port v.2 : smaller in size, usb slots are vertical, and has a detachable usb cable. 4 port v.1 : larger, usb slots are horizontal, non detachable usb cable.

Mine has all four with the blue plastic that usually indicates usb3.0. A big boon that's not advertised is that there is a second drive bay, so you can add another hard drive or even a ssd. I have added an extra drive but it took quite a few minutes to recognize it. I haven't tried it but there seems to be empty ram bays as a well.

Nothing. Someone answered that it may be USB 2.0, but I assure you the silver model is also USB 3.0. The older version of this device was 2.0, but they are exactly the same.. just this one is a cooler color! Also as far as it goes, this is the sturdiest thumb drive I've ever owned! It just requires you to keep it capped when not in use.

The product came with two USB's already connected to it. You can use both or use one. It all depends on what you are doing. I have used both USB's and one USB with ease.

I have this laptop, It have 4 USB. Also, I have 3 flash memory USB 2.0 and one hard drive USB 3.0. They all work on my laptop.

Mine is Project series and manual clearly says it is BOTH USB 1.1 and 2. However, no A/C power came with it (one reviewer said his did). Mine also came with USB cable (one reviewer said his didn't). Mine does have a volume on the Monitor Output, so (according to one reviewer) that makes it the v2 (new) version. Order mine late May, 2014.

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.

4, two are 2.0, one is 3.0 and one is eSATA/USB 2.0 (not positive the shared one is only 2.0).

One usb connector is 2.0 and attaches to any mobo header. The other is a 3.0 with a different connector which only means you must use a motherboard with a 3.0 connector or do what I did on a custom build yesterday and that was to use a 3.0 add-on card connection to a PCI-E slot.

Based on when this was introducer, I doubt it's USB 3. If your internal storage is either flash or SD, it really doesn't make much difference whether you have USB 2 or USB 3 port speed - the storage element write speed will be the gateing item.

My experience was over 2 years ago. Perhaps they are selling a different product (USB3?) compared to the one I purchased (with the incompatibilities). I recommend buying and trying.

NO, USB 2 only. The only reason USB 3 is mentioned is that it will work in a USB 3 port, but it will be USB 2 speed.

there are 4 usb ports 2 on the left and 2 on the right. the 2 on the right are usb 3.0

Even though the description says otherwise, the case I received from this page had 1 USB 2.0 and 3.0 on top. Granted, I bought this case almost 2 years ago.

I'm not 100% certain, but my guess would be that they refer to different hardware versions. The original hardware version is prone to having the USB drives become unrecognizable until you reboot and use a paper clip on the tiny reset button for the keyboard portion. This issue is supposedly fixed in the later released models.

I must say its false marketing from Asus saying it has USB 3.0 on some models when its impossible to buy it, at least no sellers on the net specify it, what I have found.. (perhaps only one model is sold in one copy and is locked in the Asus test lab in China, yeah right so much fuss for that extra *** in the finetext of the specs) Why not be more clear on what models are with USB3.0 why not name it 1015PED-U3 instead?
