I have been wanting to connect my Samsung Galaxy S2 android phone to my Alfa AWUS036H USB adapter for some time now. Having some time off recently I dived into doing this. A few things will be needed to do this mainly the following.
1…android Pcap capture
2…Micro USB Host Mode OTG Cable
3…Extra USB cables that can be cut (this may or may not be needed depending on your phone)
To start with download android Pcap capture from the play store. After this the main thing needed is a USB Host Mode OTG Cable. This can be ordered from eBay or built yourself. I decided to buy two from ebay.
Here is the site to Pcap capture. They have the requirements listed as.
“Android PCAP should work so long as:
Your device runs Android 4.0 or higher (or, in theory, the few devices which run Android 3.2). Earlier versions of Android do not have a USB Host API
You have a RTL8187 based USB Wi-Fi NIC. A good example of this is the Alfa One 802.11b/g wireless card. In the future, additional cards will be added.
You have an OTG Adapter Cable. This cable enables USB host mode on the device. Devices which have full-sized USB host ports should work without an OTG cable.
Your device supports USB Host Mode properly. Some devices do not – see the compatibility section for more information.”
My problem was I have a Samsung Galaxy S2 which has limited connectivity. I finally was able to fix this with a USB cable I added power with. Check out the video to see it. Basicaly the Black and white wires carry 5 VDC which I added by cutting a old USB cable. I did have to cut two USB and one B connector for the Alfa adapter to do this.
For the questions about the wiring I was simply adding power to the USB adapter through the wires so I had to cut them. USB carries 5 volts and red is positive and black is negative. Some phones will supply power but the Galaxy S2 I was using here would not so I had to cut the wires and ad a external power source. The phones that do supply power don’t do so for long and will drain the battery quickly so ether way it is a good idea to have a external power source to run a USB wireless adapter / dongle.
