I've try to connect a USB Stick on a Samsumg S3... it work out the box: a pop up appears on Android und leds blinking on the device.

Then I try with another smartphone with a MTK6572 (Alcatel one touch idol mini), but it didn't work. I've use the same cable and the same USB Sitck

Maybe you will be luckier... but be sure to use a OTG cable, the 4th pin (sense) must be grounded to the 5th pin (GND) on the micro USB connector.
