Product Info: 4 USB 3.0 ports, 3.1 GHZ. Product Description: 2 USB 3.0, 2 USB 2.0, and 2.0 GHZ. Contradictions here. Which are the correct specs?

I need to check it to be sure but if I recall its 2 USB 3.0, and 2 USB 2.0, not sure concerning the GHZ.

I'm not 100% tech savvy, but I think the major difference would be speed, if I'm not mistaken. 3.0 is the latest standard, isn't it? I think the transfer speed makes the difference, in which case I don't mind this one because I don't have any 3.0 USB items....I'm not much help in this matter, I just needed extra ports because I've downsized from a desktop to a laptop temporarily, so when I saw this I just grabbed it. It works quite well for what it's worth. I'm sorry if it this doesn't help.

thanks linda! I figured it was a 2.0 since the company leaves that info off the product description(accidently I'm sure...) but I wanted to make sure since the 3.0 adapters/cables are so hard to find.

Yes. It is actually rated for USB 3.0. USB 2.0 is only a data transfer rate. 2.0 can transfer 480 Mbits/sec. USB 3.0 (which is what this is rated for) transfers up to 5 Gbits/sec!

The following is from the installation booklet: Besides four default USB 2.0 ports on the I/O panel, there are two USB 2.0 headers. Each of these headers can support two USB 2.0 ports. Besides two default USB 3.0 ports on the I/O panel, there is one USB 3.0 header on the motherboard. This USB 3.0 header can support two USB 3.0 ports. Charles Newcomb

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

According to the product spec, it maintains full USB 3.0 speed for each of the four ports (2 external and 2 internal - via the 20-pin header). I haven't tested that, though.

It has 2 USB ports. One faster USB 3.0 (which works as a slower USB 2.0 port too) on the left side of the laptop, and a USB 2.0 on the right side. I never have a problem with the number of ports because I bought a Bluetooth wireless mouse and a wireless printer. Actually, I never use the USB ports at all anymore except to plug in my external hard drive to backup...

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.

It is 3.0. I suspect the box image is from a previous model. Interesting note, the USB connection is split; 1 for USB 3 and 1 for power. If you plug into the USB 3.0 port you do not need to plug in the other connection for power. The USB 3.0 powers it just fine. The extra power connection is for 2.0 connections I believe.

I maybe wrong but it looks like 2 USB2 in front and on the back. Never used USB3 before, so not exactly sure.So far, seems to work good

The initial production model had 2.0 ports. It was then updated to have 3.0 ports though remained with the same model name. Possible to get either one.

Hello Jeremy, I thought this notebook does possess USB 3.0 ports but to make sure I checked with HP at their website(http://h10032.www1.hp.com/ctg/Manual/c03534933.pdf) and this model has a total of 4 USB ports. 3 of them are 3.0 that are backward compatible with USB 1.1 and 2.0. The remaining USB port is a 2.0. Hope this help aid you in making your decision to purchase this model or not. Myself, I am quite pleased with the overall performance of this notebook.

There are 6 USB 2.0 ports and 2 USB 3.0 ports. I actually highly recommend this board, AS Rock is the sister company of Asus. The board is great for an 'above average' build for the price.
