How to Hack Wi-Fi Using Android Phone or a Tablet and External WiFi Adapter!!

Hi Null-byters,

We are much much familiar using our lappy or PC connected to an external Wi-Fi adapter and then place it in monitor mode to capture the packets and handshake which can later be decrypted using a proper brute force to obtain the password or using Reaver etc..to capture WEP enabled wifi's.

Now my question is.I had been doing that for a lot of months and now I want it to be taken to the next level I.e I want to use my tablet or smartphone(Rooted) to get connected to the external Wi-Fi adapter I know it's not that easy,I connected my adapter.TP-Link TL-WN722N Wireless USB Adapter to my tab- HP Voice Tab -7(Rooted) With Kali Linux it already,using an OTG as shown below.

But I couldn't detect it in the IWCONFIG.Has it any thing to do with the power supply (As even the LED light is also not even blinking on the adapter).

I even tried using the PCAP Capture app on my tab and it is also not detecting any external dapters as shown in the below figure.

How can I make the adapter to be able to get detected in my tab or else my phone(Micromax -Unite 2)which is also rooted and also has Kali installed.Sorry if i had said any thing wrong,i will correct it just with in your comment.Hope any of you might help,thanks in advance.
