Question 1

has anyone tried to connect them to each other to extend the length?

Accepted Answer

I think so, and it didn't work.  Its junk from China, don't buy it.  I went to Bestbuy to get something else not long after and on a whim checked to see if they had something like this (I needed 12 feet or so) and...right there in a back aisle for about 20 or 25 bucks was the 1 piece I needed work perfectly from Bestbuy.  I bought two of these cheap on amazon...and got a piece of junk from China that the computer could "not recognize" no matter how many ways I tried it.  Go to bestbuy instead and buy a reputable brand...worked for me.

Question 2

your usb extension wire has a red, yellow, green and black wire inside which one is positive and which one is negative

Accepted Answer

USB wires are generally universal with the following color reference: 
The red wire is a positive power wire with 5 volts of DC power.
The black wire is the ground wire (similar to most all electronic devices).
The white wire is a "positive" data wire.
The green wire is a "negative" data wire.
Since the wire you have has a yellow instead of white, I would expect it to be the positive.

Question 3

Question 4

Does this item provide data transfer and if so what speed?

Accepted Answer

It's a simple cord I simple USB cord and I transferred data I have no idea what speed it went except to go at the speed of my specific digital items such as my phone speed or my computer speed. It is a relatively inexpensive cord so if you're looking for something high tech I wouldn't get this one necessarily but I think it could work for average everyday use.
