I have been in the market for an OTG cable, otherwise known as a host cable for some time and I have found that the only places that seem to sell them are online only. This is not a problem half the time. I tend to do a fair amount of online shopping but for this product I was left looking for an alternative. Some sellers sold them cheap while the wait time could be as high as 30 days and others sold them for a lot more than what they are worth while the wait time was 2 days. I was looking for a middle ground. When I say a lot more I really mean you are paying more for the product than what it's worth. For those of you who don't know what a USB OTG (on the go) host cable is, it is a simple modified USB cord that has a female (most of the time) USB port on one end and a micro male USB on the other end. The types of connections on each end can differ. This cord acts as a USB port for your phone or tablet and it enables you to use external devices such as a keyboard or mouse via the female USB connector on your phone. This cord is a must have for those who want the most out of their smart phone or tablet. It works by connecting an unused pin in the micro end, to ground. Like I said it is a simple modification. Some phones and tablets do not support this function so it is wise to search the web to find if your device is compatible with this function. I explained a little as to why I was looking for an alternative to buying one online and let me go a little more in depth as to why I chose the DIY route. The top two reasons are, it would be cheaper and I wouldn't have to wait for it, You can make one for under 2 dollars with stuff you more than likely have lying around your house!
With my cable I can now use a keyboard, an xbox 360 controller and flash drives on my galaxy note 2 without any rooting. I can also use mice and other USB hardware.
You will need a Micro USB cable (in my case), a USB female port (took one off an old charger), a hobby knife, solder and hot glue and about 30 minutes of your time.
