How does it changed? a standard mini-usb?

if the question is how is it charged. You must charge it for a few hours the first time before using it. It uses a mini usb cable that is connected to a computer. However, I have not had to charge since the initial charge. I guess if you type alot you have to recharge. The manual does not indicate this. You may have to pare the tablet and the keyboard regularly. I have not had to do this either.

It seems like a mini-usb, but I am not sure if it is a standard. I have a pile of the smallish usb cables that all seem unique. I have wondered why there isn't a standard. Sorry I can't be more accurate.

The USB receiver is tiny. In my packaging, it was kind of stuffed out of the way. Take a look at the picture here to see what the receiver looks like.

I think it is more of a Mini-B USB cable. As explained in: http://en.wikipedia.org/wiki/USB#Mini_and_Micro_connectors

From descriptions, it has a mini-USB. But mini is not the same as micro. Micro-USB inputs are much flatter. They won't fit with each other without an adapter.

It is a Full Size Male USB Connector, not Mini USB. It works really good... and I find it surprising it says Mini; I don't remember it saying that back when I bought it. I hope this helps.

It fits in the regular USB port. Not mini or micro. I have it the front USB port on my desktop.

It has both ...a standard USB which is fully functional, and a miniUSB which is intended for tablet-to-computer communication, only - i.e. no power.

I think it came with a short USB cord. It's a standard micro USB anyway, you probably already have one...

Mini USB, u can either plug it into a laptop or into any wall plug with a USB port

No it does not use mini USB. It has a proprietary Lenovo charging port so you have to use the charger they give you.

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.

Regular male USB to computer. However don't bother buying this POS. Mine failed in less than a week.

It does require a USB to USB mini-b cable, which are quite inexpensive, but totally worth it. You may already have one as they go with many devices (hard drives and some phones).

Beside the USB connector its pretty much the same. I never saw the new version but it looks like it's shape may be different.

USB on one end and a very small straight pin that goes into the unit itself
